About

I turn complex
ideas into code.

Full-stack web developer with 3 years of hands-on experience designing, building, and deploying secure, production-grade web applications. I specialize in payment systems, escrow logic, and subscription platforms using Next.js 14, TypeScript, Node.js, and PostgreSQL.

As the founder of SplitPayNG, I built a Nigerian fintech platform handling real money via Paystack with AES-256-GCM encryption and automated escrow workflows. I've also delivered end-to-end freelance projects for international clients across fintech, media, and SaaS industries.

Currently completing a B.Sc. in Computer Science Education at Lagos State University (CGPA: 4.60/5.00). Always learning, always shipping.
