Development of a web application (MVP, first version of the product)

Budget: 2000 USD Deadline: 21 days

You don't just have a website here, but a foundation for a future product with a mobile app on the same API, so the key decision right now is not to quickly "stitch together screens," but to properly lay the architecture from the start.

I would implement this on Next.js + Supabase + PostgreSQL. Supabase is particularly well-suited here because of:
- the ready-made auth system
- RLS policies for protecting personal diaries
- proper scalability for a mobile app in the future
- quick MVP launch without compromising architecture quality

Claude-generated JSX is also fine - I regularly work with such artifacts. But usually, they need to be properly structured before integration: routing, state management, form validation, loading/error states, role guards, API layer, etc.

What I would lay out immediately:
- role-based access for client/admin
- secure RLS policies for diary/check-in data
- API structure for the future mobile client
- space for Stripe/WayForPay without rewriting core logic
- Sentry + analytics + backup strategy from the first version

Pay special attention to the privacy aspect - this is critical for such a product. I would recommend making it so that even the admin does not have direct access to private diary entries without a separate explicit action/logging.

I would like to clarify one point: should the AI assistant in the MVP already be a real chat flow through the OpenAI/Claude API, or is it enough to prepare the architecture and UI for integration in the next stage? Expand

Budget: 800 USD Deadline: 14 days

Hello! The project is extremely strong and has a deep social context, and the approach to development using Next.js + Supabase + Claude is 100% right for a quick and quality MVP launch. This is my main tech stack, so I clearly understand how to implement the system without unnecessary technical fuss.
Since I work at the intersection of design (UI/UX) and development, I will not just connect ready-made JSX components to the backend, but ensure that mobile responsiveness, micro-interactions, and form validation are native and comfortable for the user in a crisis state.

Why my expertise perfectly fits this brief:
1. Effective synergy with Claude: I actively use AI tools to speed up routine coding and generate documentation. Your artifacts from Claude will serve as a great foundation—I will quickly understand the existing logic, adapt components, and set up global state management.
2. Supabase & Maximum Security: Instead of writing basic infrastructure from scratch, we will use Supabase's built-in capabilities. Authorization (JWT), sessions, password recovery, and email confirmation via Resend will be deployed instantly. Role separation (Client / Admin) and endpoint protection will be configured through database-level security policies (RLS), which eliminates data leaks.
3. Universal API for Mobile and Payments: The API architecture will be built as a clean REST / JSON service. When you start developing the mobile app, it will connect to the same database without any changes on the backend. For future integration with Stripe/ЮKassa, I will pre-reserve the necessary data structures (webhooks, invoices).
4. DevOps and Legal Compliance: I will deploy the application on Vercel + Supabase, connect your domain, set up SSL, and automatic database backups from day one. I will professionally integrate Sentry for real-time bug tracking. I will also set up consent forms with policies and a Cookie banner to comply with GDPR requirements.

🎁 Free test for a quick start:
I suggest not taking my word for it, but checking my speed in action. Send me the code for one screen (for example, Home or Diary) and access to an empty Supabase. I will absolutely free of charge create a working prototype: connect the screen to the database, deploy it on a test hosting, and demonstrate real-time data interaction. You will see the quality of the code and the comfort of communication—and we will start full-fledged work.

I am ready to quickly connect, study the specifications, and start development today! Expand

Budget: 1500 USD Deadline: 21 days

Hello, I can build this MVP in Next.js/React + Supabase so that it is immediately prepared for a later mobile application through a stable API. I see that you already have JSX components and specifications, so I would start by organizing the flows, data, and permissions, and then assemble everything into a working product.

The scope I would accept: 5 screens with navigation and states, email/password auth on Supabase, client/admin roles, PostgreSQL, RLS and protection of private log entries, email notifications, a basic admin panel, deployment with HTTPS, Sentry/analytics, and handover documentation.

The most important aspect of this project will be the security of personal data and the architecture for the next stages. I would particularly ensure RLS policies in Supabase so that users cannot read others' entries through direct API queries.

Question to start: should the AI assistant in the MVP be a real chat/API already, or is a prepared support section with a place for integration sufficient at this stage?

Budget: 1500 USD Deadline: 25 days

❤️Hi, hope you are doing well

I reviewed the MVP specification and can help build the first production version of this web application using the recommended approach: Next.js/React for the frontend, Supabase for authentication, PostgreSQL, sessions, user roles, and backend data, plus email notifications, analytics, Sentry, deployment, and documentation.

Since you already have 5 ready JSX screen components from Claude, I can assemble them into a complete responsive web app with navigation, states, validation, error handling, protected routes, and clean client/admin role separation. The backend will be structured so a future mobile app can connect to the same API without rebuilding the core logic.

The MVP will include email/password registration, email confirmation, login persistence, password recovery, client dashboard flow, diary/progress/support data handling, admin panel for user management, secure access control, mailing service integration, GDPR-related pages, cookie banner, HTTPS domain deployment, monitoring, and basic backup setup.

I’m comfortable working with Claude-assisted development and Supabase, which fits your expectation for a fast 2–3 week MVP delivery. I’ll also keep the architecture ready for future payments such as Stripe or YooKassa, mobile app integration, and later product stages.

I can provide a realistic price range and timeline after reviewing the JSX components, design mockups, and full functionality specifications.

Hello! I can complete your task for a fair price. You can see examples of my work in my profile. After the project is finished, I will provide documentation and also assist with deployment on the server for 24/7 operation.

Budget: 25 USD Deadline: 14 days

Hello! The project looks very strong and well thought out. I am ready to implement the MVP of the web application using the Next.js + Supabase + PostgreSQL stack, considering future scaling for a mobile app and payments.

I have experience working with Claude-generated components, Supabase auth, role-based access, and SaaS/web-app architecture. I can assemble all 5 screens into a single stable application with an admin panel, authorization, API, and deployment.

Estimated timeline: 1-2 weeks. Price is negotiable.

I can also assist with architecture, Sentry, analytics, email flows, and preparing the project for the next stages of development.

Budget: 4500 USD Deadline: 31 days

Hello.

I have relevant experience in developing MVPs and SaaS platforms with architecture for further scaling and mobile applications. We work with the stack you specified: React / Next.js, NestJS / FastAPI, PostgreSQL, Supabase, Vercel, Railway, Sentry, Resend.

We use Claude in production processes daily — to speed up development, generate boilerplate, API layers, testing, and refactoring. There will be no issues with JSX artifacts from Claude; on the contrary, it will speed up the MVP assembly.

How we would implement the project:

Frontend: Next.js + TypeScript, adaptive PWA application for mobile-first
Backend: NestJS or Supabase Edge Functions — depending on the volume of business logic
Auth: Supabase Auth (email verification, reset password, session management)
DB: PostgreSQL via Supabase
Admin panel: separate secure route + RBAC
Analytics: GA4 + Sentry
Email: Resend or Postmark
Deploy: Vercel + Supabase/Railway
Preparing architecture for Stripe/YooKassa without rewriting the core

Separately important:

We will create a proper API structure right away for the mobile application.
We will think through security and role separation at the backend level.
We will set up database backups.
We will provide a complete GitHub repository, documentation, and access.
We will assist with GDPR/cookie/privacy policy integration.

Regarding timelines:

An MVP of this volume — approximately 2–4 weeks if there are ready mockups and final specs.

Regarding costs:

The estimate is from $4500 to $9000 depending on:

The readiness of the current JSX screens
The volume of business logic
The complexity of the admin panel
The depth of AI functionality
The necessity of real-time/chat functions
The final volume of analytics and onboarding flow.

If needed, we can also:

Immediately prepare architecture for a React Native application.
Connect an AI assistant via OpenAI API / Claude API.
Create onboarding, streak mechanics, push-ready architecture.
Prepare CI/CD and staging environment.

For an accurate assessment, we need to look at:

The current 5 screens
Specifications
User flow
Requirements for the AI assistant
An example of the relationship and progress map.

After reviewing, we can provide a fixed roadmap with stages and deadlines. Expand

Budget: 6500 USD Deadline: 24 days

Good afternoon. The cost estimate for this first version is 5500-8000 USD, and the timeline is 3-4 weeks. It can be done in 2-3 weeks if the ready JSX screens and specifications truly cover the main logic, and the AI assistant in the first version is a limited scenario, without complex therapeutic logic.

For the task, I see not just the assembly of screens, but a product MVP - Next.js, Supabase Auth, and PostgreSQL, client and admin roles, a diary, daily check-ins, progress tracking, support, a secure admin panel, email notifications, deployment, SSL, Sentry, analytics, and documentation. The API should be designed so that the mobile application can connect later without reworking the database and authorization.

I would like to clarify two points. Should the AI assistant already be in the MVP as a full chat with history and safety rules, or is it enough for now to have an integration point and a simple support scenario? And should the admin only view and block users, or also edit diaries, progress, and program modules?

Similar cases to consider are Ingello - https://business.ingello.com/rapport - a platform for psychologists and patients, closely related in terms of sensitive data and support roles. https://business.ingello.com/lita-doctor - doctor offices and connection with the user application, similar in roles, data, and service logic. Indirectly, also https://business.ingello.com/vorfahr - SaaS with offices, payments, and scalable architecture.

The main page of Ingello for Freelancehunt - https://systems-fl.ingello.com

I would simplify it - first, I would briefly check your Claude components and specs, after which I would finalize the scope of the first version and the risks. If the materials are in good condition, the working estimate is around 6500 USD and 24 days. If it needs to be compressed to 2-3 weeks, we can highlight the essential core of the MVP and move some functions to the second step. Expand

Budget: 1500 USD Deadline: 14 days

Hi there!

I can turn your five ready screen components into a real working MVP that feels calm, safe, and reliable for users, with a backend that is ready for the mobile app later. I am comfortable working with Claude generated JSX and cleaning it into a consistent Next.js codebase with solid state handling, form validation, and clear error messages on both desktop and mobile.

For the backend, Supabase is a strong fit here because we can use Postgres plus Row Level Security to protect diary entries and check in data so one user can never read another user’s records even if they try to call the API directly. I will set up email sign up, email confirmation, login with session, password reset, and role based access so the client area and the admin area are strictly separated. The admin panel will let you view users, block or unblock, and review client data safely. I will also wire email sending through a provider like Resend or Postmark, add Sentry for monitoring, connect analytics, and deploy with SSL on your domain.

One idea that will make the product feel more trustworthy is a Privacy First Journal Vault. Each diary record is stored with strict access rules, plus an optional private mode where sensitive text is masked in admin by default and only shown if the admin explicitly unlocks it with a reason that gets logged. It is easy to explain, it fits the topic, and it shows real care for user safety.

https://app.cookiecad.com

Budget and timeline estimate: around $1500 to $3000 depending on how complete the specs are for the diary, progress charts, and support screen, delivered in about 2 to 4 weeks with a usable build in the first week.

Thank you! Expand

I created Poseidon (https://poseidon.codezerogroup.com) — an enterprise web app with a multi-role dashboard, JWT authorization, and API integrations — exactly the architecture needed for a psychological platform with client/admin roles and a modular 12-step program.

Next.js + Supabase is the right choice: RLS at the database level protects log entries so that the admin cannot see others' data without explicit permission — important for such sensitive content. You already have 5 JSX components — I focus on integration, backend, and infrastructure.

What I will do:

- 5 screens: Main (daily check-in), Route (12 modules), Journal, Progress (charts), Support (AI assistant + booking)
- Auth: email/password, JWT, email confirmation, password reset, Supabase Auth
- 2 roles: client/admin, endpoint protection on the backend, admin panel (user list, blocking, preview)
- Backend: Node.js/NestJS or FastAPI, PostgreSQL, REST API ready for mobile, architecture for Stripe payments
- Infrastructure: Vercel + Railway, Resend/SendGrid, Sentry, Google Analytics, DB backup from day one
- GDPR: consent, privacy policy, cookie banner, HTTPS, protection against XSS/CSRF/SQL injection
- GitHub repo + API documentation + deployment instructions + all accesses

--- OPTIONS ---

- Option A (MVP): 1000 USD (9 days) — 5 screens, auth, 2 roles, Supabase, deploy, email, documentation
- Option B (Standard): 1600 USD (14 days) — like A + AI assistant (Claude/OpenAI), full GDPR, Sentry + Analytics, automatic backup — best scope/price ratio
- Option C (Premium): 2080 USD (18 days) — like B + admin panel for managing modules, progress reporting, API endpoint for future mobile app

Completion time: 9 days (MVP). To start: 5 JSX components, mockups, access to the domain.

Olga, good afternoon!
The project is very interesting and, to be honest, completely within our profile. We are the Coderfy team and specialize in complex web/mobile products with thoughtful architecture and further scalability.
We have already had experience in a similar niche, developing an application for a psychologist, which included personal notes, schedule management, client interactions, and internal processes. Additionally, we have extensive experience in developing complex mobile and web applications with authentication, roles, analytics, chats, progress tracking, and admin panels.
Your approach with Claude + Supabase is also close to us — we have already worked with AI-generated code and know how to properly turn such MVPs into maintainable and scalable products, rather than just a "glued prototype."
It is also very correct that you are immediately laying the architecture for the mobile application and future payments — this greatly affects the API structure right from the start.
Regarding the timeline for an MVP of this level — approximately 3–5 weeks depending on the state of the current screens and the depth of business logic. As for the budget — it’s better to discuss after reviewing the specifications and artifacts from Claude, because here not only the UI matters, but also security, roles, architecture, and the quality of the backend part.
We are ready to get involved, conduct a quick audit of the current base, and propose an optimal roadmap for launching the MVP 👍

The task is clear: we need to assemble ready screens into a working web application with authentication, roles, an admin panel, and a database, so that in the future we can easily connect a mobile application and payments.

I can do this using Next.js + Supabase to quickly launch the MVP and not waste time on complex infrastructure. There will be registration, login, password recovery, role separation (client/admin), a secure admin panel, email newsletters, and a proper deployment with a domain and SSL. I will also prepare an API to easily add a mobile application later.

Hello!

My name is Alexey, and I represent the NC-1 development group. For over 5 years, we have been building modern web applications, e-commerce platforms, and AI-integrated products.

Your technical approach is exceptionally smart. We are fully aligned with the Claude + Supabase workflow. Our team regularly uses Claude artifacts to accelerate frontend development, and we are experts in Supabase architecture (RLS policies, JWT auth, and PostgreSQL). This allows us to cut down basic infrastructure costs and fit perfectly into your 2–3 week timeline.

Our MVP Implementation Strategy:
Frontend: We will take your 5 ready-made JSX components from Claude, establish clean state management (tracking progress for the 12 modules, diary inputs, mood check-ins), and ensure premium mobile-first responsiveness.

Future-Proof API & DB: Using Supabase, we will build a universal database schema. When you launch your mobile apps later, they will connect to these exact same endpoints without backend refactoring.

Admin & Security: A dedicated admin panel strictly protected by user roles. We will set up automated daily DB backups and reserve architectural space for future payment gateways (Stripe).

Production Readiness: Resend/SendGrid for transactional emails, HTTPS domain mapping, GDPR-compliant cookie banners/consent forms, Google Analytics, and Sentry for error tracking.

Fixed MVP Budget: $6,609 USD

Timeline: 15–18 working days (approx. 2.5 calendar weeks)

Budget: 1000 USD Deadline: 15 days

Hello, Olga!
Your project is exactly the type of MVP I specialize in: structured, scalable products that need to be launched quickly while keeping the architecture ready for future mobile applications and paid features.

I have extensive experience with:
Next.js + React frontend development
Supabase (authentication, PostgreSQL, storage, row-level security)
Node.js / API architecture
Admin panels and role-based access management
Secure authentication systems
Production-ready responsive SaaS applications
Development workflows using Claude

Your approach using Claude + Supabase is perfect for creating a high-quality MVP in 2–3 weeks, especially considering that 5 screens already exist as JSX artifacts.

I can integrate, refactor, and deploy them into production, turning them into a maintainable application with proper architecture and security standards.

Proposed technology stack:
Frontend: Next.js + TypeScript + Tailwind
Backend/API: Supabase + Edge Functions / Node.js where necessary
Database: PostgreSQL (Supabase)
Authentication: Supabase Auth with email verification + session storage
Admin panel: Secure admin panel with RBAC
Mail service: Resend or SendGrid
Monitoring: Sentry
Analytics: Google Analytics
Deployment: Vercel + Supabase/Railway
Security: Validation, rate limiting, XSS/CSRF protection, HTTPS

I will provide:
A fully responsive web application
Authentication + password recovery
Separation of client and admin roles
Secure backend/API ready for mobile integration
Admin panel for user management
Documentation + deployment instructions
Access to the GitHub repository
Production deployment with SSL/domain setup
Legal pages compliant with GDPR and consent handling
Scalable architecture prepared for future payments (Stripe/YooKassa)

Estimated timelines:
MVP development: 2–3 weeks
Testing + deployment: 3–5 days

I am ready to start immediately and can first review the existing screens and specifications created by Claude to formulate an accurate action plan.
Looking forward to further discussing the project.
Thank you. Expand

Budget: 100 USD Deadline: 7 days

I read the technical specification — a web application MVP with 5 screens, backend for a future mobile application, registration/password recovery/email confirmation, two roles (client/admin), email notifications, readiness for Stripe payments in the next iteration.

The basic stack I will assemble:

- Backend: FastAPI + SQLAlchemy + Alembic migrations, PostgreSQL, JWT authentication with refresh tokens, password hashing via argon2/bcrypt.
- I will design the API universally with versioning (`/v1/...`), so the mobile application can connect without rework. Pydantic schemas as a contract.
- Email: Postmark or Resend (more stable than SendGrid for transactional emails) — confirmation, reset, notifications.
- Frontend: I will assemble 5 screens from your existing artifacts into a single SPA with routing, form validation, error handling, and responsiveness.
- Admin panel: a separate set of endpoints with `Depends(require_admin_role)`, role checking on the backend not only in the UI.
- Security: rate-limiting via slowapi on /auth endpoints, CSRF for cookie sessions (or JWT-only without CSRF — we will discuss), XSS through Content-Security-Policy headers, SQL injection closed via SQLAlchemy parameterization.
- Deployment: Render or Railway — for PostgreSQL + backend + frontend with one config. I will connect Sentry + Google Analytics as part of the finalization.

One question for a more accurate assessment: is the format of the artifacts from Claude already React components, JSX, or HTML/Tailwind layouts? Expand

I have reviewed your project — it is a very strong product with a clear structure and good MVP logic.

I work with similar full-stack systems (React/Next.js + backend + Supabase/FastAPI), so I can take on the full cycle: from building the UI to API architecture, authorization, roles, and deployment.

Why I can do this better than others:
- I immediately lay down the right architecture for scaling (mobile app, payments, AI)
- I use Supabase / modern stack to avoid wasting time on unnecessary infrastructure
- I quickly assemble MVP without losing code quality
- I create a clean structure that is easy to hand over to another developer without "chaos".

Hello, I have developed applications of this type multiple times with the corresponding stack.
Please write to me in private messages, and we will arrange a call to discuss the details. I also need a design for evaluation.
I will be happy to help you!

Greetings! I am a website and application developer with experience - I am in the TOP-10 on freelance!
I am ready to develop the MVP of your web application using the Next.js + Supabase stack. I am well acquainted with the rapid development approach through Claude and effectively integrate the JSX components you have already created.

What I will do:
I will set up Supabase (Auth, JWT, PostgreSQL) and design a universal API with a focus on the mobile application.
I will configure roles (Client/Admin), adaptive navigation, Resend for emails, and lay the architecture for future payments.
In the future, I will gladly develop a mobile application (React Native) on the same backend.

Timeline: 2–3 weeks. I will propose a budget range in the chat.
Ready to start!

Hey Olga,

Read the spec carefully. The Claude + Supabase workflow you're describing is exactly how I work daily, so the tooling expectation isn't a stretch on my
side, it's an advantage. I can take the JSX artifacts you have and integrate them properly rather than rebuilding them.

A few thoughts before I commit to numbers:

The domain matters here. This isn't a standard CRUD app, it's an emotional product handling sensitive data from women going through divorce. That
changes how I'd approach error states, copy in edge cases, and what the admin is allowed to see. Diary entries especially should be encrypted at rest
with a key the admin can't read by default, otherwise you've built a tool where a support person can browse intimate journal content. That's a small
architectural decision worth getting right on day one.

Two scope questions before I lock in:

The AI assistant on the Support screen — for MVP, is this a scripted flow with safety guardrails (crisis detection, escalation to a real psychologist),
or just a basic Claude API chat? The first is realistic in 2-3 weeks; the second is a few days. The first is also the only responsible version for
this audience.

The admin panel scope — view + block users + view client data is straightforward. Editing diaries or progress data is a bigger ethical question (and a
different feature). Worth confirming before I build.

How I'd structure it:

Next.js 14 App Router for the frontend, integrating your existing JSX screens. Supabase for auth, PostgreSQL, and row-level security (RLS rules so
clients can never see other clients' data). Resend for transactional email. Stripe-ready architecture (placeholder routes, no implementation yet).
Sentry and GA from day one. Vercel for hosting, Supabase handles the DB and auth side.

GDPR coverage: cookie banner, privacy policy template, consent checkbox on registration, data export and deletion endpoints (required, often forgotten
in MVPs).

Domain bound, SSL via Vercel automatic, GitHub repo handed over with deployment docs.

Long-term collaboration works well for me. The mobile app on the same backend down the line is a natural extension if the API is designed right from
the start, which it would be.

Happy to clarify the two scope points above whenever convenient Expand
