Why I build

I build tools so software feels obvious at 2am, when you're stressed and want it to just work. Cloudflare taught me how a real edge platform behaves under load. Side projects taught me what people actually open more than once. I care about building things that are small, durable, and worth coming back to. I ship in public and write down what I learn along the way.

Selected work

Four projects I keep coming back to. Edge infrastructure at Cloudflare, a logging tool I built because Datadog priced me out, an AI portfolio generator, and the Telegram bot that taught me what shipping at scale really means.

Notes I wrote down so I'd stop forgetting them: shipping, edge platforms, and the tools I reach for when something breaks at 2am.
