Senior Java developer at FPT Software building authentication and transaction systems for Hyundai US.

Vietnam

Message

At FPT Software, I work with Hyundai US to build and enhance authentication, user login, and transaction management systems. I engineered API Gateway mediation layers for authentication and account lifecycle flows across multi-brand platforms.

I refactored API request processing and strengthened server-side token validation. I also added distributed tracing and ELK structured logging, and developed Cucumber regression and integration tests.

At Flexton Inc, I supported Sam’s Club’s credit application platform across web and mobile. I developed Spring Boot APIs and Azure services, deployed containerized applications on AKS, and integrated external credit bureau and internal financial systems.

Earlier, at K2view LLC, I implemented Java and SQL ETL pipelines for telecom data migrations. At Robert Bosch Engineering Vietnam, I developed Java microservices for manufacturing monitoring and analytics; at Simple Solutions Taipan Vietnam, I delivered backend solutions for event management and volunteer coordination.
