02About

I'm Clinton Owoseni, a Full-Stack & Mobile Engineer with 3+ years building production web systems. My work spans the complete stack - Postgres schemas, Express middleware, Next.js interfaces, React Native screens, and the Docker-backed dev infrastructure that holds it all together.

I lean toward product-thinking. The systems I build don't exist to demonstrate a pattern - they exist to solve a real problem for a real user. That means taking every layer seriously: the schema design, the auth flow, the loading state, the edge case at 2AM.

Previously at Nobox Labs and Xerax Labs. Currently building Resumify independently - a multi-platform SaaS with both a web app and a native mobile client sharing a single backend.
