About Me
Passionate About Clean Code & Great Design
I'm Alex Chen, a full-stack developer based in San Francisco with over 5 years of experience building web applications that are both performant and delightful to use. I specialize in React ecosystems, Node.js backends, and cloud infrastructure on AWS.
My approach combines technical excellence with a deep understanding of user experience. I believe great software should feel invisible — solving problems so seamlessly that users barely notice the technology behind it.
When I'm not coding, you'll find me contributing to open-source projects, writing technical articles, or exploring the latest in AI and machine learning.
