NTT_DATA

Software Engineer for Financial Systems

NTT DATA • Full-time

Nov 2021 - Present • 4 yrs 6 mos

Last Deliver case: How I Built a Real-Time Payment Interoperability System for a Top Colombian Bank THE PROBLEM: Colombia's banking system required a federated directory for low-value interbank transactions, compliant with Central Bank regulations. The challenge: real-time performance, regulatory compliance, and zero tolerance for transaction failures. MY ROLE: Lead Backend Engineer — responsible for microservice architecture, data layer design, and integration with the national payment network. THE SOLUTION: Designed and implemented BRE-B using Java/Spring Boot with MongoDB and SQL, enabling secure, near-real-time settlement between participating banks. The system passed Central Bank compliance review and went live in production. TECH STACK: Java | Spring Boot | MongoDB | SQL | Microservices | REST APIs THE OUTCOME: ✔ System approved by Colombia's Central Bank regulatory review ✔ Production deployment with 4+ yrs stability at NTT DATA ✔ Enabled interoperability for low-value transactions across multiple banks
