About

Developer who bridges
software & quantitative finance

I'm a fullstack developer based in Nairobi, Kenya, with 4+ years of experience shipping high-performance cross-platform applications. From mobile banking platforms to AI-powered learning tools, I build systems that handle real users and real money.

My curiosity extends into quantitative trading — applying statistical analysis, algorithmic strategies, and machine learning to financial markets. I bring the same engineering rigor from production software to building and backtesting trading systems.

Currently building Ticha — an AI-powered learning platform transforming documents into interactive learning experiences, live on App Store and Google Play.
