About Me

Software Engineer /
Full-Stack / AI

I'm a software engineer based in Lagos, with a background in Electrical Engineering and a systems-first approach to building software. Over the past 5+ years, I've built and shipped fintech platforms, cross-platform mobile apps, and LLM-powered systems used by real people and businesses.

I care about more than getting things to work in a demo. I focus on building reliable, scalable products that hold up in production — from the architecture and infrastructure to the details users interact with every day.
