👨‍💻 About

Senior Frontend Engineer with 8+ years of experience building and scaling production-grade web applications.

Most recently, I worked as a Founding Senior Frontend Engineer on a real-time AI platform, building the frontend from scratch and scaling it to ~1M users. I focus on system design, performance, and real-time applications, going beyond UI into architecture, reliability, and data flow.

Strong experience with React, TypeScript, SSR, and WebSockets, as well as analytics systems, payment flows, and frontend infrastructure.
