01 — About

A developer who builds with purpose

I'm a Full-Stack Developer and Computer Science graduate from Lagos State University with hands-on experience building complete digital products — backend APIs, web dashboards, and mobile apps. My primary backend language is C# with .NET 8 and ASP.NET Core, and on the frontend I work with Next.js, TypeScript, and React Native.

My flagship project, Vendify, is a complete e-commerce platform I built across three codebases — a REST API, a Next.js web dashboard, and a React Native mobile app — with real payment integrations (Paystack, Flutterwave, Stripe) and live deployments. I've also built a Student Progress Tracking System with role-based access and live deployment, and an AI-Powered PDF Editor.

I'm open to Backend, Frontend, Full-Stack, API, and Mobile roles — locally in Nigeria and internationally. I adapt quickly, write clean code, and take projects from idea to deployment. Currently expanding my skills through Microsoft certifications.
