About

A product-minded engineer who likes shipping real things.

I'm a software engineer based in the Netherlands with more than a decade spent building mobile products and the systems behind them. I've worked across international teams — from Istanbul to Hamburg to Amsterdam — shipping apps used by millions.

I care as much about product and craft as I do about clean architecture. Today I'm the founder of LoneWave, where I design and build independent software end to end — from the first idea to the App Store.
