I build scalable mobile and web products across marketplaces, fintech, AI, and real-time verification.

I've built mobile and web products for Hanaja, NaijaShop, Squad (GTCO), and Autogon AI. At Hanaja, I guided a system rebuild through architectural audits, TypeScript migration, and Playwright validation.

I've owned core customer, rider, vendor, and operations interfaces, launched mobile deployment pipelines, and improved data performance for high-volume fintech transactions. My work includes products such as Medgnosis, Agrointel, Microwd, and a GTCO Fashion Week vendor directory used by over 700,000 fashion enthusiasts.
