About

Isaac Epaphras Nana Sam

I'm a full-stack software developer with over 4 years of experience building web applications and production systems. I studied Computer Engineering at KNUST, graduating with First Class Honours.

Most of my work is in TypeScript, React, and Next.js, though I'm equally comfortable on the backend. I've shipped systems across healthcare, fintech, and crypto. More recently, I spent time at Bespoke Labs building AI agent evaluation environments on Kubernetes, which was a different kind of engineering challenge.

I tend to gravitate toward work where the constraints are real: regulated environments, government systems, live financial infrastructure. Outside of client work, I build things on the side, mostly web tools and experiments.
