About
I'm a senior full-stack engineer based in Nairobi, Kenya, with over six years of experience designing, building and shipping web applications across the TypeScript ecosystem — from front-ends in React, Next.js, Remix and React Native to back-ends in Node.js, Hono, PostgreSQL and MongoDB.
Today I'm at Angaza Elimu, building the tools curriculum teams use to author learning content, and the platform that delivers it to tens of thousands of students every day.
I care about software that makes a difference and is a joy to use. Away from code, I write — about engineering, and about nature, meaning and the sacred.
