About

I'm a frontend engineer based in Lagos with a thing for interfaces that actually feel good — responsive, animated, and built to last. The last two years I've been shipping across agencies, fintechs, and a handful of products of my own.

Web is home: Next.js, TypeScript, Tailwind. But mobile is where it gets interesting — I build with React Native and Expo, and there's something about shipping to a pocket-sized screen that keeps me excited. I also build Chrome extensions, because sometimes the browser itself is the product.
