About

Professional summary

I am a full-stack software engineer based in Abuja, Nigeria, with production experience delivering web applications from responsive user interfaces through backend services, testing, and cloud deployment.

I work primarily with React, Next.js, TypeScript, Node.js, NestJS, PostgreSQL, MongoDB, Supabase, and REST APIs. I enjoy translating product requirements into reliable, maintainable features that solve real user problems.

I have contributed to SEO-focused Next.js applications, CMS platforms, fintech performance improvements, safety-platform backend infrastructure, and enterprise portals. My work includes server-side rendering, caching, authentication, access control, API integrations, and automated testing.

I am also interested in applied AI and AI governance. I have built and continue to develop systems involving LLM-powered functionality, AI agent policy enforcement, approval workflows, audit logging, and reliability evaluation.

I am comfortable collaborating remotely with cross-functional teams and working autonomously in fast-paced product environments. I value clean architecture, accessible interfaces, performance optimization, security-minded development, and shipping production-ready software.

I am currently pursuing a bachelor's degree in Network Technology and Cybersecurity while expanding my full-stack engineering and cloud development expertise.
