At SecurePay, I'm leading the architecture and development of a next-generation payment gateway designed for 10,000 TPS and 1 million users. I manage a team delivering financial transaction services with Java 21 and Spring Boot.

Previously at SecurePay, I designed and enhanced payout and payment gateway services, reducing API response times by about 40% through database query optimization and caching. At Safexpay, I developed product features using Java, Spring Framework, and Angular JS, and supported banking API integrations.
