Worked on the apache/bigtop-manager repository, focusing on backend development and DevOps improvements over a three-month period. Delivered a JWT-based authentication feature by implementing a configurable utility class for secure token generation and validation, using Java and the Spring Framework to enhance service security. Addressed maintenance by cleaning up the Data Access Layer, removing deprecated APIs and obsolete types to simplify the codebase and reduce onboarding complexity. Improved CI reliability by refining Docker container cleanup scripts with Shell scripting, ensuring robust removal of test containers. The work emphasized disciplined refactoring, security hardening, and operational reliability across backend and infrastructure layers.

Jun 1, 2025June 2025: Focused on container cleanup robustness in the apache/bigtop-manager project. Implemented a fix that alters the docker ps filter from -q to -aq to ensure all bm- containers on the bigtop-manager network are removed, regardless of running state. This corresponds to BIGTOP-4440 and is committed in docker/containers/build.sh (a78d6f7949f9eec85f54675de4906b3b4055e852). The change reduces risk of orphaned containers, prevents environment drift in CI/CD and local testing, and improves reliability of build and test workflows.
