available for backend rolesBackend engineer who turns messy domains into reliable APIs.
Java & Spring Boot, nearly 4 years building and maintaining enterprise insurance systems. I design clean, layered services, tune performance, and sweat the trade-offs behind every endpoint.
Experience
Backend services in Java, Spring Boot, SQL Server, MongoDB, gRPC & RabbitMQ — premium-calculation and authentication modules. Code reviews, production issue investigation, and 3 months onsite in Switzerland as the bridge between the CH and VN teams during a critical go-live.
Built insurance features across Spring Boot, JavaFX, gRPC, RabbitMQ, Liquibase & Docker with JUnit/Mockito coverage. Diagnosed defects and refactored the UI to stay responsive on large datasets.
