/ 03 — About

Operator's
manual.

/ Background

I'm a software engineer with 0+ years of experience building web apps, developer tools, and the unglamorous middle layers that keep systems honest.

/ Care about

›Performance & correctness over speed of shipping
›Honest design — no dark patterns, no tracking pixels
›Writing clearly about complicated things
›The boring parts that make things last

/ Currently

Writing software for a living. Writing about software for myself. Reading too much. Available for interesting problems and the right kind of trouble.
