I build high-agency product engineering teams that excel at speed and ownership to build the best.
01 / ABOUT
I'm the person who looks at your microwave and wonders if it can run Doom.
Most often, it can.
I work close to product, architecture, and team design: enough strategy to keep direction clear, enough hands-on engineering to keep decisions grounded.
Outside the day job I keep building — projects big and small, like Kanarek.app. If I need something, I build it: full-stack tools, data-viz experiments, and things with real design care. And I love giving back, whether through open source or the wider community.
