I build software that runs in real time.

I'm a junior Computer Science student at UC Riverside and a full-stack developer who likes owning a system from the data layer to the interface — live transit data pipelines, WebSocket bot platforms, and native C++/JNI tooling for anticheat testing. I work across Python, TypeScript, C++ and Swift.
