Senior Fullstack Software Engineer at Paga, building payment infrastructure and a virtual-account collections engine for SME invoicing.

Nigeria

Message

At Paga, I build and maintain React/TypeScript interfaces and Java/Spring Boot services for core payment infrastructure. My work spans ledger mechanics, AML/KYC flows, Nigerian payment rails, and the microservices architecture and API contracts behind internal and partner-facing applications.

At Carbon (formerly Paylater), I built and maintained loan origination and repayment APIs serving over 10,000 users per day, and led the migration of legacy endpoints to microservices. At Fortunae Technologies, I developed a hotel-booking API and integrated Paystack, processing 1,000+ secure transactions daily.

I also built a personal SME invoicing MVP: a microservices-based collections engine that generates virtual accounts per invoice and integrates with Monnify's sandbox. I’ve worked across fintech, gaming, and telecommunications, including secure transaction systems, short-code allocation workflows, and event-driven services.
