MVP AI-coach working MVP chatbot with GPT-4. "Phoenix"

Budget: 100 USD Deadline: 1 day

Hello, I worked on a GPT-4 chatbot for online consultations, 5 stages and 40 dialogues, with history saving, all on React.

How do you plan to integrate Stripe for accepting payments in your MVP?

I suggest we get in touch, I will consult you for free on the technical side and we will create a development plan + I will tell you about my team!

Budget: 500 USD Deadline: 14 days

Hello! I’m an experienced Full Stack Developer specializing in AI integrations (GPT-4 / GPT-4-Turbo) and React + Node.js / Next.js applications. I can deliver a fully working MVP chatbot within the first week and refine it to a production-ready version in the second — including onboarding flow, chat UI, stage selection, history storage (Firebase / Supabase), and Stripe integration.

I’ve previously built AI chatbots and GPT-based apps with custom logic, memory, and admin panels, so I can ensure a clean architecture and smooth UX.

&Tech stack: React / Next.js, Node.js, TypeScript, Firebase, OpenAI API

Looking forward to collaborating and delivering a polished AI product ready for launch!

Hello!

We are The Dev Company, a team of 4 full-stack developers with extensive experience in TypeScript, JavaScript, Node.js, as well as frontend development using Next.js and Vite. We specialize in integrating OpenAPI into SaaS products, CRM systems, and applications, and we can fully implement your MVP chat in 14 days.

How we will implement the project

–> Stage 1 — Preparation (1-2 days)
– Analysis of the technical specifications, clarification of the logic of stages and UX flow.
– Setting up the environment (Next.js + TypeScript + Node.js API routes).
– Connecting Firebase/Supabase for authorization (registration via email).

–> Stage 2 — MVP Chat (3-7 days)
– Creating the main chat interface (UI based on best-matchmaking.com).
– Implementing onboarding (3 steps + stage selection with 6 buttons and emojis).
– Integrating OpenAPI with the ability to choose any model (GPT-4-turbo / GPT-4o).
– Saving the history of dialogues and the current stage of the user.
– Setting up the system prompt and basic response logic.
– Internal testing of the MVP and optimizing UX.

–> Stage 3 — Completion and Improvements (8-14 days)
– Connecting Stripe for payment processing.
– Adding a simple admin panel for editing stages and messages.
– Testing logic, UX, and integrations (AI, Stripe, Firebase).
– Optimization, deployment, and preparation for demonstration.
– Final check and presentation of the working prototype.

Tech Stack
–> Frontend: Next.js, TypeScript, React, Tailwind/Vite.
–> Backend: Node.js (API routes Next.js).
–> AI: OpenAI API (GPT-4-turbo / GPT-4o).
–> DB/Auth: Firebase or Supabase.
–> Billing: Stripe.

Timeline: 14 calendar days (MVP version — by the end of the 1st week).
Cost: from $300 to $500, depending on the depth of integration (Stripe, admin panel, analytics, etc.).

Ready to start immediately after clarifying the details and providing the technical specifications.

Sincerely,
The Dev Company Expand

Hello,

I’m interested in developing your GPT-4 chatbot MVP. I’ve built multiple AI chat and onboarding systems using Next.js, Node.js, and OpenAI API (GPT-4 / GPT-4-Turbo), with Firebase for authentication and chat storage, and Stripe for subscription/payment integration.

Your 2-week plan is realistic — I can deliver a functional prototype within 5–7 days, then finalize the MVP with testing, content, and Stripe integration in the second week.

✅ Tech stack: Next.js, Node.js (Express), Firebase, Stripe, TailwindCSS
✅ Deliverables: Responsive web app with onboarding, 6-stage chat logic, saved chat history, and optional admin tools.

Estimated rate: $800–$1,000 for the full MVP, depending on scope details.
I’m also open to long-term collaboration for post-launch features.

Kind regards,
Jeo Vincent Carretas Expand

Hello!

I have experience creating chatbots with GPT-4 and developing MVPs quickly and efficiently. I can create a working prototype in 7 days and refine it for full launch in another week. I have worked with React, Next.js, Node.js, Firebase, Stripe (payment integration), and created bots with email registration and custom onboarding.

I will send a portfolio with examples of similar projects in private. I am ready to start immediately, will consider all your wishes, will deliver the MVP on time, and then help with development: testing, admin panel, Stripe integration, and expanding functionality.

The cost is negotiable depending on the required configuration, please write for clarification of details!
