About

Engineer, writer, founder.

I build software that removes drag from real work. Most of that lives at the intersection of AI, automation, internal tools, and product systems.

I'm based in Kigali, Rwanda. At Andersen Rwanda, I work on AI automation for research, compliance, and market analysis. The work I enjoy most is the kind that turns a repetitive process into a dependable system.

Outside that, I'm building Daylens, a local-first time tracking product for Mac and Windows, and shipping essays and working notes about AI, product craft, and building in public.

I care about clarity, speed, and software that feels trustworthy. That usually means fewer features, stronger defaults, and a bias toward things that hold up under real use.
