I build useful software and the hardware behind it.

I'm Daniel, a software engineer and hardware hacker working across health data, travel tools, AI, DePIN, and robotics.

I co-founded Hotspotty and DePIN Hub, and I ship independent apps including DaysAbroad and VitalTrends. This is where I share the work and what I learn along the way.
