I build fast, reliable web products end to end.

I'm a full-stack engineer working across TypeScript, React and Node. I spend most of my time on the unglamorous half of product work — data models that hold up, APIs that stay predictable under load, and interfaces that stay quick on a mid-range phone.

Have something to build?

I take on a small number of freelance projects alongside my full-time work. If the problem is interesting, I'd like to hear about it.
