I’m an Associate Technical Consultant focused on building reliable, end-to-end backend solutions using Java and Spring Boot. At Oracle, I developed scalable Spring Boot REST APIs that keep data flowing smoothly between Oracle FLEXCUBE core modules and external banking systems.

I translate complex, bank-specific business rules into robust backend implementations that extend core banking functionality for multiple global clients. I also configure and deploy Java/Spring Boot applications on Oracle WebLogic Server, managing deployment lifecycles to support high availability in secure environments.

In my projects, I’m drawn to correctness, performance, and clean systems. I built an event-driven Spring Boot media pipeline using RabbitMQ, SSE, Docker, and an event-driven architecture to avoid blocking server threads and eliminate database polling for live progress updates.

I’ve also engineered an idempotent fintech webhook engine that guarantees exactly-once execution using distributed locking (Redis SETNX) with concurrent webhook handling and test coverage via JUnit. I enjoy collaborating with Agile teams and documenting work with tools like Jira, Confluence, and Scrum workflows.
