About

I’m a frontend engineer with 7+ years of experience building and owning high-risk, data-intensive web applications, especially in React and TypeScript. I’ve worked across fintech, SaaS, gaming, ad-tech, and consumer platforms—focusing on performance, correctness, and UX where those factors directly affect revenue, trust, and operational stability.

In my recent roles I’ve owned core areas of real-time systems (including live-market financial products), designed frontend architecture from the ground up, and built resilient UI patterns around streaming and data-heavy experiences. I enjoy translating product requirements into maintainable engineering solutions, defining frontend–backend data contracts, mentoring teammates, and collaborating closely with product and design to ship reliable features end-to-end.
