Engineering Fintech Platforms & Intelligent Systems

Full Stack Engineer | Fintech, Fraud Systems & Geospatial Development

Building Production-Grade Systems Across Fintech and Spatial Technology

I'm a Full Stack Engineer focused on building production-grade fintech platforms — designing backend APIs, integrating machine learning models into real-time fraud detection pipelines, and developing the frontend interfaces that tie it all together. I work across the entire stack with a strong emphasis on system architecture, code quality, and scalability.

My path here started in Geomatics Engineering, which gave me a rigorous foundation in complex data systems, spatial analysis, and precision thinking. Since 2019 I've delivered 500+ projects — spanning freelance consulting, corporate GIS development, and now fintech engineering — for clients across 20+ countries. That range sharpened my ability to move fast, solve hard problems, and communicate clearly across technical and non-technical audiences, carrying me from a GIS Developer role into my current focus: full stack engineering for fintech platforms.

I hold a Bachelor of Science in Geomatics Engineering and GIS from Jomo Kenyatta University of Agriculture & Technology, and I'm currently reading for a Master of Science in Financial Engineering at WorldQuant University — the quantitative side of the work I already do day to day. I'm also certified in Software Engineering and Data Analytics. I still take on geospatial work when the problem is compelling, but building fast, reliable systems for high-stakes financial decisions is where I spend most of my time.
