At Payaza, I built and maintained card-acquiring infrastructure integrating Mastercard, Visa, Interswitch, Habaripay, and N-Genius. I also built First Bank direct routing, which improved authorization success rates by 60%.
I designed a foreign-exchange rate management service for multi-currency card processing and built an automated reconciliation service that reduced manual effort by 90%. I also led the N-Genius acquiring integration covering authorization, capture, refunds, and settlement.
At Ecobank Nigeria, I implemented the Nigerian National Payment Stack integration with NIBSS using ISO 20022, including secure message flows and a compliance monitoring system. I also optimized the NRBVN service for international customer onboarding.
At Mobilise, I designed the Hero database schema for multi-tenant MVNE operations and delivered platform components, including backend services, billing integrations, and compliance logging. Earlier, at Woodcore inc., I built multi-tenant banking and payment systems, including Pooler, loan processing, and reconciliation tooling.
