About Me

A Data Science student at the University of Nairobi with strong interests in software engineering and fintech. I'm passionate about coding, mathematics, and applying data-driven problem-solving to real-world fintech challenges.

My hands-on experience is grounded in building full-stack applications and configuring ISP systems, constantly seeking to bridge the gap between robust engineering and insightful data analysis.

My Philosophy

I believe technology is a tool for problem-solving, and the best solutions arise from a deep understanding of the fundamentals. My approach is rooted in first principles, much like in mathematics and physics. I strive to build software that is not just functional, but also elegant, efficient, and maintainable.

My journey into data science has taught me that at the core of every complex system lies a story told by data. Whether I'm architecting a backend service or designing a user interface, I am always thinking about the flow of information and how it can be leveraged to create more intelligent and intuitive experiences.
