Alex Chen
Full Stack Engineer building performant web applications and developer tools. Currently crafting interfaces at Vercel
Previously shipped products at Linear, Stripe, and early-stage startups. I care about clean code, fast load times, and thoughtful UX.
When not coding, you'll find me contributing to open source, writing about web performance, or exploring new frameworks.
