Hi, I'm Collins, a software developer who turns ideas into real-life products. For the past three years I've been building web apps, mobile apps and the odd web3 experiment for clients across continents.

I care about clean interfaces, buttery transitions and the small details that make people stay. Most days you'll find me deep in Next.js, React Native and Expo — usually with something on repeat in the background.
