What I'm looking for

I'm seeking a senior, remote-friendly technical role leading full-stack teams to build scalable, user-centric web and mobile platforms, ideally in tech-for-good or high-impact sectors.

I'm a Full Stack Developer and Tech Lead with 6+ years in full stack development and 3 years in technical leadership, focused on delivering reliable, performant systems for high-impact sectors.

I led backend and frontend work on high-volume services—including contributions to Safaricom's M-Pesa App—and built BizHub KE, a major business directory platform. I specialize in Node.js, Express, Angular, GraphQL and MongoDB, and design cloud-native architectures on Azure with transferable GCP experience.

I champion clean code, CI/CD, peer reviews and documentation while mentoring teams to align engineering with product goals. I'm passionate about tech-for-good and seek opportunities to apply engineering to humanitarian and high-impact initiatives.
