Senior Backend Developer at SureBanka building payment APIs for 500K+ users and NIBSS interbank transfers.

Nigeria

Message

At SureBanka, I design and ship .NET 10 payment APIs for mobile and web banking used by 500K+ people. I integrated NIBSS interbank transfers and BankOne intrabank services, and built Azure Service Bus pipelines that cut manual reconciliation effort by 60%.

I also own deployment reliability at SureBanka: releases are gated on automated tests, with an ADR and thorough review required for every code change. I’ve maintained 99.95% uptime on critical payment rails while strengthening authentication, audit logging, and fraud-prevention controls.

At Limestone Ltd., I led 12 engineers and owned architecture decisions for a multi-tenant SaaS platform. I helped migrate its monolith to microservices, tripling scalability and reducing production incidents, while improving performance through query and architecture optimization.

In independent projects, I built a WhatsApp automation platform for a crypto OTC trader and am developing a fuel-station fraud-prevention platform spanning pump hardware and distributed backend systems. The fuel platform uses Go, NATS, PostgreSQL, and MQTT, and is currently in internal pilot testing.
