It took two years and half a dozen doctors to figure out I had a rare disease. So I tested how good Claude is at diagnosing rare-disease cases using only public medical tools — and audited what the published benchmarks actually measure.

How I tuned my Claude Code agent setup to keep my side projects rolling while exploring Berlin from cafés, trains, and bike rides.

I've wanted to have a place on the web that makes it easier to connect with people (and agents). This is the start of a basic personal site where I hope to do that!

Navigating Berlin with our four-year-old, the "good" bike routes from Google Maps kept dropping us onto painted bike lanes on major roads. So I spent about 32 hours over a few weeks building a prototype that finds actually-quiet routes for families with young kids.

Notes on how I structure my charitable giving — donating appreciated stock through a Donor Advised Fund, why I weight international causes more heavily than domestic, and what the tax mechanics actually are. Written for friends who've asked how this works.
