Summary

Engineer based in Nairobi with a background in systems programming (C, Python) from the ALX Software Engineering programme, now working across the stack: Laravel and TypeScript back ends, React and React Native front ends, and applied AI. Most of my recent work is agentic: tool-calling agents, the memory and orchestration layers underneath them, and the tests that prove they recover when tools fail.
