At Newway, I built the fullstack project, backend systems for wallet, payment, and digital service platforms in Nigeria. I designed and deployed scalable APIs for real-time wallet transactions, bill payments, subscriptions, and verification services.

I improved system uptime from 97% to 99.9% through database and query optimization, reduced payment failure rates by 30% with better retry logic and transaction handling, and introduced test-driven development practices to improve API stability and reliability.
