About: I’m a frontend engineer drawn to the complexity of modern UI systems.

This space is primarily for frontend engineers who already know the basics and want to think more deeply about systems, not just tools.

I write about frontend architecture, performance limitations, developer experience, maintainability, and the trade-offs that arise as applications grow.
