The challenge
Build a marketplace people can trust: find the right expert, talk in real time, and pay safely, all in one place.
The approach
Three production apps (a customer platform, an admin dashboard, and an Express API) share one PostgreSQL database. Expert matching runs on Gemini embeddings and pgvector for natural-language search, payments use Stripe Connect with scheduled payouts and dispute handling, and Redis, BullMQ, and Socket.IO power background jobs and live messaging.
The result
A full marketplace shipped end to end, from architecture and database design through backend, frontend, infrastructure, and deployment.
