About

Hyrox Berlin, 2025

👋 Mark here -- dad-in-training, code-curious, always trying to move forward.

Dabbled in several endurance races and wandered to some far-flung places from Yemen to Japan to Nicaragua. Always curious, always trying to move forward.

Worked as a chartered surveyor, teacher and now taking a swing at startup life. Recently, I learned to code with AI, and now I ship Hyrox products I need - maybe you do too.

Inspired by quiet builders and laptop freedom: Levels, Friks, and Lou 💻.

When I'm not coding, I'm training for Hyrox or knee-deep in a LEGO mission with the kids.
