I built ChatCom, a real-time chat backend with public, private, and one-to-one rooms, message editing, paginated history, and reconnect sync. I implemented cookie-based JWT authentication, refresh-token rotation, email verification, password reset, and Google OAuth2 login.
My projects also include ShopNetic, a multi-role e-commerce backend with SKU-level inventory and checkout workflows, and a distributed API gateway with Redis rate limiting, circuit breaking, and tracing exported to Jaeger. As a Technical Team Member at Team SARK, I coordinated technical events and workshops and collaborated on technical projects.
