ABOUT ME

I build things, lead people, and never skip coffee.

I'm a senior full-stack mobile engineer with 5+ years building products that people actually use. I've led cross-functional teams, architected scalable systems, and shipped apps across multiple countries. My philosophy is simple: write clean code, empower the team, and never lose sight of the user.

When I'm not in a pull request or planning a sprint, you'll find me on the tennis court, deep in a book, hunting for the best coffee in Kigali, or in a late night conversation that somehow solves everything.
