What I work on

I help founders and operators ship software that earns its keep. Most of my work is full-stack: architecture, frontend, backend, infrastructure. The thread connecting it is a bias toward small bundles, native web platforms, and systems that keep running when nobody is watching.

I write the long form here. Most pieces document a decision I made on a real project: why I picked it, what it cost, what I would do differently. The goal is not to lecture; it is to make the trade-offs explicit so the next person can decide for themselves.
