About

I'm a software engineer with years of experience building web applications and leading engineering teams. I work on developer tools and infrastructure.

I've worked at startups and larger companies, learning a lot along the way, and I write about those lessons here.

When I'm not coding or writing, you can find me reading books, watching movies, listening music, adda with fnf, experimenting with photography, or trying to make the perfect cup of coffee.
