What I'm looking for

I’m looking to build scalable payment, collection, and real-time transaction systems where I can deepen my backend engineering impact.

At Xpress Payment Solutions, I build e-collection and POS payment platforms used by more than 10 banks across Nigeria. My work supports state-level collections for Oyo, Delta, Ogun, and the Nigeria Revenue Service.

I’ve extended collection APIs to POS terminals, built Pay-with-Transfer capabilities alongside card payments, and led development of a Terminal Management System supporting hundreds of terminals across client locations. I also built a real-time POS notification service integrated with Parallex Bank and integrated Vertebra’s electricity token service into Xpress Biller.

I bring a Computer Science background and hands-on experience designing REST APIs, payment integrations, transaction services, and internal business systems.
