About

I'm a Senior Frontend Engineer with 6+ years of experience specializing in high-performance React and TypeScript applications. I like architecting large-scale browser-based editors and scalable state management systems, with a constant eye on performance and maintainability. Lately I've been focused on building AI-powered product experiences and weaving agentic workflows into how software gets built.
