01 — about

A developer who hopes his work will be useful to someone.

I've spent the last few years on the backend — REST APIs, auth, queues, scrapers and live video for client products — plus a stint writing ESP32 firmware for a research institute. Now I'm building my own things: a hobby journal, a job-hunting pipeline, small tools anyone can use. Curious, prolific, self-directed.
