Project Description: I am looking for a full-stack developer (or a small team) to build an MVP for a specialized C2C gaming marketplace for the European market. The app will focus on buying, selling, and swapping video games with automated metadata and secure payments. Key Features to Implement: Smart Cataloging: Integration with IGDB API. Users must be able to scan a barcode (EAN) to auto-fill game details (Title, Console, Publisher, Year, and Market Value). Secure Payments (Stripe Connect): Implementation of an escrow system. The platform holds the funds until the buyer confirms the item's condition. Must support automated split payments (Seller's payout + Platform commission). Trade/Swap Engine: A dedicated system where users can propose "Game A + Cash" for "Game B" based on real-time market data. Logistics Integration: Automated shipping label generation (API integration with SendCloud, InPost, or DPD). Chat & Profiles: Real-time chat for negotiation and a trust-based rating system. Technical Requirements: Frontend: Cross-platform (Flutter or React Native). Backend: Node.js, Python (FastAPI/Django), or similar. Database: PostgreSQL or Firebase with efficient caching to minimize API costs. UI/UX: Clean, "gamer-centric" design, optimized for mobile. What I am looking for: Someone with proven experience in Stripe Connect (Escrow/Marketplace flows). Experience with third-party API integrations (IGDB, Shipping providers). Ability to provide a scalable architecture and a clear timeline for the MVP. Please provide: Examples of previous marketplace or fintech apps you’ve built. A preliminary estimate for the MVP development (Phases & Cost). Your preferred tech stack for this project.

Hello, Building a high-stakes C2C marketplace goes beyond listings, it needs solid escrow logic and an intuitive Swap Engine tailored for gamers. I’ll develop your MVP using Flutter for a seamless iOS/Android experience, with a Node.js/PostgreSQL backend designed for complex game metadata and trade flows. For Smart Cataloging, I’ll integrate IGDB with a custom wrapper and caching layer to reduce latency and API costs. For payments, I’ll implement Stripe Connect (Custom Accounts) to manage escrow and automate split payments while maintaining full UX control. I’ve built several marketplace systems with multi-party payments and logistics, happy to share details privately. Before estimating, I have a couple of questions: 1. For EU shipping, should we prioritize InPost lockers or standard door-to-door carriers? 2. Do you have design references or wireframes for the UI? Best, Niral

I can build a full-stack MVP for your C2C gaming marketplace that integrates essential features such as secure payments and smart cataloging with IGDB API. My experience in API integration and marketplace solutions positions me well for your project. I will implement a smart cataloging feature that allows users to scan barcodes, automatically populating game details. This will enhance user experience and streamline the listing process. For secure payments, I will leverage Stripe Connect to create an escrow system, ensuring that funds are held until the buyer confirms the condition of the item. This will also facilitate automated split payments, making transactions transparent and efficient. The trade/swap engine will allow users to propose game exchanges based on real-time data, promoting engagement within the platform. Additionally, I will integrate logistics solutions for automated shipping label generation, enhancing operational efficiency. Quick question: What is your preferred tech stack for the project, particularly for the backend and database? I can share relevant web dev work on request.

Hello, most marketplace MVPs fail at payments and data flow—escrow, splits, and real-time listings break if not structured right. You want a solid C2C gaming marketplace with smart cataloging, secure Stripe escrow, swaps, shipping, and chat—all working smoothly from day one. I’d build this with Flutter (fast cross-platform UI), Node.js (NestJS) + PostgreSQL, and caching (Redis) to control IGDB costs. Stripe Connect (Custom accounts) for escrow + split payouts, barcode scan → IGDB autofill, and shipping via SendCloud/InPost APIs. Real-time chat using WebSockets/Firebase, with a modular setup to scale later. Result: a stable, scalable MVP with working payments, listings, and trade flow. I can prototype the listing + Stripe escrow flow first so you can validate core logic. Do you want to launch with buy/sell first or include the swap engine in MVP?

I’m Hossam, your reliable and experienced backend developer who can give life to your C2C gaming marketplace! While my expertise lies in Laravel and MYSQL, I am adaptable and efficient in handling a variety of tech stacks. In terms of frontend, I propose using Flutter—an innovative and highly customizable framework that will ensure a smooth cross-platform experience for your European audience. One of the key features of your platform is secure payments (Stripe Connect). I have hands-on experience with it, having developed fintech applications utilizing similar escrow and automated payment systems. Interfacing other third-party APIs like IGDB, and shipping providers (SendCloud, InPost, DPD) is another one of my skills since I’ve worked on projects requiring multi-layered integrations. Besides technical competence, I regard myself as an architect who understands the importance of scalability and efficiency. My understanding of database structures alongside efficient caching reduces API costs. Also, the "clean and game-centric" UI/UX design you desire aligns with my commitment to delivering high-quality work. So let’s collaborate to bring your MVP to life in a timely manner while ensuring maximum functionality and user satisfaction.

This is a solid MVP idea with clear monetization, and the complexity mainly sits in payments, marketplace logic, and integrations rather than just UI. I’ve worked on marketplace-style and transaction-based apps where secure flows, real-time interactions, and third-party integrations are central. For your case, I’d propose a scalable architecture using Flutter for cross-platform UI and a Node.js (or FastAPI) backend with PostgreSQL to manage users, listings, trades, and transactions. For smart cataloging, I’d integrate IGDB API alongside barcode scanning to auto-fill game metadata and enrich listings. Stripe Connect would be used to implement the escrow flow with split payments, ensuring funds are held and released only after buyer confirmation, along with platform commission handling. The trade/swap engine would match listings using real-time pricing logic, allowing users to propose combinations of cash + games. Real-time chat can be implemented with WebSockets or Firebase for negotiation, and shipping label generation can be integrated via APIs like SendCloud or similar providers. UI/UX would be designed with a clean, gamer-focused aesthetic, optimized for mobile, with smooth flows for browsing, listing, trading, and checkout. For MVP delivery, I’d break it into phases: core marketplace + auth, cataloging + listings, payments (Stripe Connect escrow), then chat, trades, and shipping integrations. Syed
