Problem
What needed to be solved
The project is now a backend-first marketplace platform, so the main challenge was organizing real API boundaries for roles, products, carts, orders, reviews, authentication, persistence, and documentation.
Solution
How the project approaches it
I structured MarketHub as a layered ASP.NET Core API with EF Core data access, PostgreSQL persistence, JWT-secured role flows for Admin, Vendor, and Customer users, Swagger API documentation, Dockerized development, unit tests, and a GitHub Actions CI workflow.

What I learned
Technical takeaway
I learned to approach marketplace work from the API contract first: clear layers, explicit roles, predictable persistence, and repeatable verification make the platform easier to test and extend.
