Designed, built, and shipped WeLynk

Designed, built, and shipped WeLynk solo, a production social platform live on web, iOS, and Android. Owned everything end to end: FastAPI services, PostgreSQL/Redis, React and Flutter clients, WebSocket real-time layer, deployment, and observability. The platform combines real-time chat and presence, voice and group calls, matchmaking, 10 first-party games on an in-house SDK, virtual currency, subscriptions, and internal moderation and analytics tooling. 2.1M+ lines of code across Python, TypeScript, Dart, Rust, and Luau. Zero application-caused outages since launch.
