  • Work closely with DevOps to ensure seamless CI/CD pipelines using GitHub, Maven/Gradle, Jenkins, etc.

  • Collaborate with UI developers on React-based front ends

  • Write unit and integration tests using JUnit, Mockito, TestNG

  • Maintain and troubleshoot existing applications with JSF front ends

  • Provide documentation and architecture diagrams for modernization roadmap
