A developer at heart.
A builder by habit.

For more than fifteen years I've built software for the way people work. Today that also means the small routines of everyday life: fasting and nutrition with Atomic Fast, and shared travel with TripMath.

I started as a developer, became a product maker, and now lead a group of companies. I still ship, I still write, and I invest in founders who build. More about me

Useful software. For everyday life.

Less trip math. More time together.

A simpler way to keep track of group travel expenses. Record spending in plain language, split costs across currencies and see who owes whom.
