HENDRIK KRACK DEVELOPER ADVOCACY

I help people adapt technology.

Hendrik Krack. I talk to developers about AI code review, write about developer tools and climate-aware engineering, and build demos that break in interesting ways.

about

I work at the intersection of AI developer tools and the people who build them. I turn what fast-moving teams are shipping into talks, workshops, and demos developers can actually trust. Before advocacy, I wrote test software for automotive chips and researched wireless interference at NXP — I still write code most weeks, mostly so my demos break honestly.

Off the clock: climate advocacy, cycling, and an unreasonable number of RSS feeds.
