Simple Marketplace + Map + Services Mobile Platform (MVP)

Hello!
I am a Flutter frontend developer and I am interested in working on your MVP.

From my side, I can implement:
1.) Mobile client (Flutter)
✔️ Marketplace (listing, card, cart, checkout)
✔️ Map-based discovery
✔️ Booking flow
✔️ Profiles & services
… ✔️ Feed (posts / likes / comments)
✔️ Role-based UX (User / Seller / Provider)
✔️ Authorization
✔️ Payment integration (Stripe via API)

2.) Web admin panel (Flutter Web)
✔️ User management
✔️ Moderation of products and content
✔️ Location management
✔️ Booking control

Important
I focus on the frontend part:
- mobile application
- web admin panel
- client logic
- working with roles at the UI level
- integration with backend API

I do not develop the backend, but I can work in conjunction with your team.
I am ready to discuss the details of collaboration — please write in private messages.

If this is assembled without the proper architecture — in 6 months everything will have to be rewritten.

Realistic MVP assessment (without over-engineering, but with a scalable foundation):
Timeline: 4–6 months
Budget: $55,000 – $90,000
(depends on the depth of roles, payments, and feed model)

Team needed:
• Senior Mobile (Flutter or React Native — with marketplace/booking UX experience)
… • Backend Engineer (Node/Nest or FastAPI, clear role & permission model)
• Frontend for Web Admin (React / Next)
• QA
• UI/UX (to avoid turning this into “features without a product”)

MVP can be simplified to 3–4 months ($35,000+), if:
– make booking basic
– simplify feed
– minimize seller onboarding
– integrate Stripe without complex commission logic

The key is to design correctly:
– role model
– permission architecture
– billing flow
– future scalability of the marketplace

Hello!
We are the Coderfy team, specializing in the development of MVPs and scalable mobile platforms with booking services and role-based systems.

We have practical experience in creating:
- marketplaces with sellers and a cart
- booking services for specialists and locations
- map-based platforms
- mobile applications with user roles
- admin panels for moderation and content management
…
We offer the implementation of an MVP on React Native or Flutter with a reliable backend and web admin panel. We work specifically with the approach of Proof of Concept → scaling to a full product, without overloading with unnecessary features.

We resonate with your approach: first, testing the hypothesis, then developing the product. We know how to separate what is necessary for the MVP from what should be left for the next stages.

We propose to discuss the details of the MVP (priority modules, roles, payments, admin panel), after which we will provide an exact calculation of costs and timelines.

Hello!

I have reviewed the requirements for the MVP: a cross-platform application (iOS/Android) + web admin panel, which combines a simple multi-seller marketplace, a map with partner locations and booking slots, a catalog of services/specialists with reviews, a light feed (posts, likes, comments, moderation), role-based access (User/Seller/Service Provider/Admin), and in-app payments (Stripe or similar).

We are SplineStudio (20+ years in the market, a team of 30–35 people), we create MVPs “turnkey” + further support with established delivery and a separate QA/Assurance function; for your project, we offer a team consisting of PM/Delivery Lead + Flutter Developer + Backend (NestJS/FastAPI, PostgreSQL) + QA (if needed UI/UX and part-time DevOps) and we can implement this for a fixed price of 420,000 UAH ($9,707, including a service fee of $960) with a timeline of 10 weeks (~50 working days).

To ensure this is a PoC/MVP, but with a foundation for scaling, I propose:

Mobile: Flutter (fast, stable, one codebase for iOS/Android) or React Native — if there is a strong reason.
…
Backend: NestJS (Node) or FastAPI (Python) + PostgreSQL, a clear permission model with roles.

Admin panel: a web panel for users/moderation/locations/bookings/basic analytics.

Approach in stages (to avoid inflating the MVP):

Fixing the scope of the MVP: user scenarios, minimum data entities, role/access rules, a list of “definitely doing / postponing.”

Platform framework: auth, roles, basic admin panel, database/API structure.

Marketplace: listing → card → cart → checkout + simplified seller onboarding + moderation.

Map & Booking: a map with categories, location card, slot booking, confirmation.

Services directory: profiles of specialists/services, bookings, reviews.

Feed light: posts with photos/videos, likes/comments, basic moderation.

Payments: Stripe/similar, payment statuses, webhooks, “release-ready builds.”

What can be made cheaper/faster without losing concept validation:

postpone video in the feed (leave photos),

postpone part of the analytics in the admin panel,

limit booking to one type of slot at the start,

decide on payments right away: one-merchant or marketplace payouts (Stripe Connect) — the second option is significantly more complex.

I am ready to briefly go through the requirements and immediately propose the final MVP specification and sprint plan. Everything described above is tentative and subject to adjustments until approval.

Hello!

I am a Full-Stack Software Engineer with over 7 years of experience in developing websites, SaaS solutions, complex web platforms, and MVPs for startups - from idea and architecture to production and support.

I work not only as a developer but also with a focus on business logic, scalability, and long-term support of solutions. My portfolio includes examples of implemented projects of varying complexity.

Technology stack:
PHP (Laravel, Symfony, Yii2),
Frontend: JavaScript (Vue.js, React.js), HTML5, CSS3,
… Databases: MySQL, PostgreSQL.

Regarding timelines and costs - at this stage, it is difficult to accurately assess them without clarifying the requirements. To form a reasonable estimate, it is usually necessary to understand:
- the goals of the project;
- key functionality;
- expected load and integrations;
- priorities (quick launch vs scaling).

I suggest starting with a brief clarification of requirements or a call/email - after that, I will be able to provide a realistic estimate on timelines, budget, and implementation options.

I would be happy to discuss the details.

Hello, Snezhana.
Your MVP is a Swiss Army knife, where the most challenging part is not the product listing, but the combination of Map + Booking + Roles. If you make a mistake with the architecture of these nodes at the start, the project will turn into a patchwork factory by the time you reach the first thousand users.
My team and I specialize in systems where the map and real-time are the foundation. Our flagship case is a full-fledged equivalent of Yandex.Taxi (admin panels, logistics, 24/7 support). We are used to systems that cannot go down, and the data on the map must be up-to-date to the second.
Why you should discuss the project with us:
For your Map-based discovery, we will offer solutions that do not overload the frontend with a large number of points.
In taxi projects, we have implemented complex access levels (Driver / Client / Dispatcher / Technical Support). We will transfer this experience to your Role-based access in just a few days.
We understand where savings can be made (for example, on simplified onboarding) and where they cannot (on transactions and protection against double bookings).
The code is open, and our work style can be seen here: github.com/vitalivo.
If you are looking for not just coders, but a team that understands how to turn a concept into a scalable business - let's chat privately. I will show you how we implemented similar modules in our admin panel for taxi services.

Hello,

I’m a solo developer with experience building MVPs for marketplaces, booking systems, and map-based platforms. I focus on delivering lean Proofs of Concept that validate the idea while keeping the architecture scalable.

I can build a cross-platform mobile app (Flutter or React Native) with a modern backend, role-based access, Stripe payments, and a lightweight web admin panel. The MVP will prioritize core flows only, avoiding unnecessary complexity.

I’m interested in a long-term partnership and phased development beyond the MVP.

Best regards,
… Jeo Vincent Carretas
