I build secure, high-throughput fintech payment systems with Java.
NigeriaWhat I'm looking for
I've built payment capabilities at Redtech and Interswitch, including PayPal and Ercas international gateway integrations, secure account operations, transaction services, and payment reconciliation. My work supports real-time, compliant financial transactions across merchant and consumer platforms.
At Synova Technology Solutions, I built REST APIs that reduced server load by 30% and improved request processing by 50%. I also integrated Paystack for wallet creation and lender-borrower transfers, improving transaction processing time by 15% and reducing payment errors by 25%.
I build Java and Spring Boot microservices with Kafka, REST APIs, observability, encryption, 2FA, and PCI-DSS-aligned security practices. I'm continuing my M.Sc. in Information Technology and learning German as I prepare to contribute payment-domain experience to a high-growth engineering team in Germany.
