I ship ideas, build high-performance systems, and lead products from 0 to 1. My work spans the entire vertical stack, from TS, Go and Rust backends, React or Vanilla JS Frontends, to AI-driven orchestration and industrial-grade UX.
This is a collection of my best work that was shipped or made for graduate-level CS classwork.
