NigeriaWhat I'm looking for
I’m a mid-career Software Engineer and Web Application Developer who builds and deploys full-stack web applications across the MERN stack. I’ve delivered production-ready projects with responsive frontends, RESTful backends, and real-world user experiences—especially through React component architecture, client-side routing, and UI/UX collaboration.
As a freelance developer, I’ve built and deployed business and social web applications, including platforms with email/WhatsApp integrations and live deployments to Vercel for fast, reliable access. I’m currently expanding my expertise with Next.js and the PERN stack, and I enjoy shipping projects that blend secure authentication, CRUD functionality, and AI-integrated user value.
