The
Engineer
Behind
The System

I'm Success, Head of IT at Airvend (formerly Callphone Limited) — a Nigerian fintech company where I lead a team of 7 engineers and oversee infrastructure that processes over 100,000 transactions daily.

My work spans backend architecture, mobile development, DevOps, and security hardening — connecting Nigeria's telecoms (MTN, Airtel, 9mobile, Glo), financial institutions like NIBSS, and payment gateway services into reliable, scalable systems.

I've grown from IT Support Specialist to Head of IT, building real fintech products along the way — not just maintaining them.
