Worked on the JobService/job-service repository to deliver targeted backend improvements focused on secrets caching and build tooling. Implemented enhancements to the in-memory secrets cache using Java, introducing enum-based secret keys, auto-eviction, and a configurable maximum cache size to optimize memory usage and ensure predictable cache behavior under load. Updated configuration to allow flexibility in cache management, supporting future scalability. Additionally, aligned the build process with current environments by upgrading the docker-version-maven-plugin, ensuring smoother deployments without impacting user-facing features. The work emphasized backend development, caching strategies, and configuration management, establishing a stable foundation for future feature expansion and operational reliability.
