About

Building products that solve real problems

I'm a full-stack product builder based in Nairobi, Kenya. I work at the intersection of software engineering and UI/UX design, which means I don't just build what you ask for; I help figure out what you actually need.

My background spans web development, system design, and product thinking. I've built everything from internal tooling for enterprises to consumer-facing products, always with a focus on the people using them.

When I'm not building, I'm writing about the intersection of technology and the African market, particularly how informal economic structures shape digital product design.
