I am a Senior Software Engineer with 15+ years of experience specializing in the modernization of mission-critical financial systems. I bridge the gap between legacy stability and modern cloud scalability, with a proven track record of transitioning monolithic J2EE architectures to Java 21/25 microservices on AWS EKS.
- Legacy Modernization: Expert in decomposing monoliths using the Strangler Fig pattern and refactoring legacy XML/J2EE into modern Spring Boot.
- Distributed Systems: Implementing Event-Driven Architectures with Apache Kafka and ensuring data consistency via the Outbox pattern.
- Financial Domain: Deep knowledge of regional banking integrations (Southeast Asia), including CCRIS, CTOS, and ISO8583 compliance.
- Cloud & DevOps: Architecting resilient systems on AWS (EKS, Fargate, Aurora) with automated database lifecycles via Flyway.
