About
I’m a full stack software engineer based in Abuja, Nigeria, focused on building fast, secure web applications end-to-end. I work primarily with JavaScript/TypeScript and modern frameworks like Next.js and React, and I integrate backend services using Node.js, Express, NestJS, and REST APIs, with data stored in PostgreSQL and MongoDB.
Across my roles, I’ve delivered production-ready features, improved performance with client-side caching and lazy loading, and supported scalable deployments using AWS, Docker, and platforms like Vercel. I also enjoy taking designs from Figmas into clean, reusable UI workflows, and I’m actively strengthening my cloud and security fundamentals through ongoing certifications.
