Building scalable systems, driving technical excellence

I'm a software engineer with 5+ years of experience architecting and delivering production applications used by thousands of users. From real-time multiplayer platforms to enterprise ERP systems, I focus on building performant, maintainable solutions that solve real problems.

I believe in engineering fundamentals — clean architecture, type safety, and thoughtful abstractions. When I'm not shipping features, I write about JavaScript internals because understanding the 'why' behind the code makes the difference between a good engineer and a great one.
