Relevant portfolio (marketplace or transaction-based systems preferred) 2. Your proposed tech stack and architecture approach 3. Estimated timeline with phases 4. Experience with marketplace payments - escrow workflows 5. Brief explanation of how you would handle payment lifecycle: * payment - hold - fulfillment - release - dispute handling NOTES * We are not only looking for the cheapest option. Quality and correctness are critical. * Placeholder bids without understanding the system will not be considered. * Long-term collaboration is possible after initial build. If you have built systems where payments, trust, and user interactions are critical — we would like to hear from you.

Hi there, We’ve developed several marketplace platforms with advanced features like multi-role user systems, dynamic listings, and integrated payments. One of our recent projects, Descripio, involved building a Chrome extension that used AI to extract product data from Amazon and eBay, allowing sellers to optimize their listings based on competitor insights. We also understand the importance of a strong admin panel for managing users and listings, as well as for dispute resolution. We’ve built fully-featured admin dashboards that allow super admins to manage all aspects of the platform. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m looking forward to hearing more about this exciting project.

This is a multi-category marketplace where listings, payments, and trust flows must work seamlessly across verticals like property, motors, jobs, and services. The real challenge is designing flexible data models without breaking scalability. I’ve built similar transaction-driven systems where Stripe Connect + role-based dashboards required strict reliability and auditability. I’d build an API-first backend using Node/NestJS with PostgreSQL for strong transactional integrity. Category-driven schema with extendable attributes keeps each marketplace vertical flexible without constant migrations. Stripe Connect would run through a clear state machine (hold → verify → release) driven by webhooks. Messaging and notifications would be handled asynchronously for reliability and smooth UX. AWS deployment would stay modular to support scaling and future mobile expansion. Happy to map the full architecture flow before we proceed. Q1: Dynamic category attributes admin-managed or fixed schemas? Q2: Escrow model: time-based, confirmation-based, or hybrid? Q3: Dispute handling: basic admin or full audit trail?
