About

p.1/3

I'm an engineer who likes building things end-to-end, from early problem framing to the tooling, platforms, and delivery details that make software work in the real world. Eleven years in, I still believe great systems come from sweating the small details until they disappear.

Outside the editor, I am usually exploring DIY builds, biotech, retro computing, bonsai, or going deep on a new tool. I write occasionally about systems, taste, and the craft of building useful software.
