What we built
- A Flutter mobile client and a web front end on one versioned API.
- A NestJS API with Prisma and PostgreSQL: accounts, listings and orders.
- A digital marketplace infrastructure that brings different event sources together, letting users discover events and evaluate resale ticket listings.
- Marketplace payment integration prepared for provider approval.
Engineering notes
- 01
One consistent discovery experience
Events from different sources are presented in one consistent search and browsing experience on mobile and web.
- 02
Staged launch by design
Trading, payments and service fees are separate switches with explicit states, so the platform can open step by step.
- 03
Predictable performance
Requests to event sources and page rendering run with strict limits and timeouts, so pages stay responsive.
