At Vaulsys (Vendor for NayaPay), I designed and developed RAAST P2M CSP and MSP Request-To-Pay APIs for real-time digital payments between merchants and consumers. I also worked on Visa Scan N Pay and Visa Direct Remittance APIs for QR-based and cross-border payments.
I lead the development and maintenance of core systems including the switch and wallet, as well as their non-financial APIs. My work also includes card-based transaction APIs for e-commerce, POS, international transactions via Euronet, and domestic transactions through 1Link.
Previously, I gained experience maintaining a production-level stock trading feed server at Logiciel Services, LLC, and worked as a Full Stack Developer Intern at Syslab.AI. I also built GigPilot, a freelance marketplace using Java, Spring Boot, ReactJS, Tailwind CSS, and MySQL.
