Hi, I'm

Alex Chen.

Software Engineer & Open-Source Builder

I design and build fast, accessible web products — from pixel-perfect interfaces to the APIs and infrastructure behind them. Currently focused on developer tooling and performance.

About me

A short version of the longer story.

I'm a software engineer with 6+ years of experience shipping products used by millions of people. I care deeply about the craft — clean architecture, thoughtful interfaces, and the small details that make software feel effortless.

These days I spend most of my time in TypeScript, React and Node.js, with a healthy amount of Go and Rust on the side. I also maintain a few open-source libraries and write about performance and developer experience.

When I'm not at a keyboard, you'll find me hiking, brewing coffee, or reading sci-fi.
