Backend Engineer | Computer Science Student at Kisii University
Hey! I'm a CS student based in Kenya, turning real-world problems into reliable software solutions.
Background
I'm a Computer Science student at Kisii University with a strong focus on backend engineering and software architecture. What fascinates me most about software is the hidden layer that powers everything behind the scenes — the systems, APIs, databases, authentication mechanisms, and business logic that make applications actually work.
I enjoy building practical solutions to real-world problems and continuously sharpening my engineering skills through personal projects. My stack spans Node.js, Spring Boot, and Django — giving me a broad view of different backend ecosystems and their tradeoffs.
I believe in simplicity and maintainability over chasing unnecessary complexity. As Terry Davis put it: "Idiots admire complexity, geniuses admire simplicity." I try to solve the problem directly in front of me before reaching for abstractions.
