About Me

Turning complex
problems into elegant systems

I'm a full-stack developer and AI systems builder based in Nairobi, Kenya. I specialise in designing and building high-performance applications — from real-time dashboards and M-Pesa payment integrations to AI-driven data visualisation platforms. I care deeply about clean architecture, performance, and systems that scale.
