I've built and deployed scalable web and cross-platform mobile applications for Cromtech & Analytics Systems, serving 100k+ monthly active users.

I architected Node.js and Python RESTful and GraphQL microservices that reduced core API latency by 35%, while leading React, Next.js, and Tailwind CSS work that cut page load times by 40%.

I design secure PostgreSQL and MongoDB data systems, OAuth2/JWT/RBAC authentication, and AWS deployments with Docker and automated CI/CD pipelines, maintaining 99.95% production uptime.

My project work includes real-time AI conversational platforms, a healthcare diagnostic portal, industrial surveillance using computer vision, and a news analytics dashboard. I also led a 12-developer team on an industrial monitoring platform that won 2nd Place nationally in Nigeria.
