About Me

A Builder Across All Frontiers.

I'm a multi-disciplinary software engineer based in Nigeria with 5+ years crafting products that sit at the intersection of great design and powerful technology. I've shipped production apps in web, mobile, and AI domains.

From full-stack web platforms deployed on Vercel to Flutter mobile apps with SQLite-local privacy-first architecture, to AI-powered civic tech products integrating Google Vertex AI & blockchain — I bring the full engineering stack to every engagement.
