I teach engineers to read code the way I learned to read it: slowly, with notes in the margins.

02 — Currently

Working on.

Twelve years writing kernel and runtime code in three languages. Two of them spent teaching graduate systems courses at TU Berlin — work I left to ship at Cloudflare, and work I came back to when we founded Lattice.

Most of my career has lived inside the operating system. I joined Cloudflare's runtime team in 2019, and I'm still there one day a week — embedded in scheduler work for the next-generation Workers platform. The other four days are Lattice.

I didn't plan to start a school. The plan was to teach the seminar I wished I'd taken — three weeks, eight engineers, one hard problem. The plan grew. We've done eleven cohorts since.

What I teach is mostly the discipline of patience: how to read assembly without flinching, how to profile something rather than guess at it, and how to be honest with yourself about whether you understand what you're looking at. It turns out most performance problems are not problems of cleverness but of looking carefully at the right thing.

I'm Director of Curriculum at Lattice, which mostly means I argue with my co-founders about what to assign and what to cut.
