Senior Front End Engineer

Hi, I'mJohn Lam.

Building high-quality frontend systems that stay fast, maintainable, and reliable as products and teams scale.

I'm a front-end engineer with a passion for intuitive, scalable UX and creative storytelling. Outside of work, I co-create Humans of Windsor with my partner and shoot with my Sony A7III while contributing to open source.
