Contributed to the apache/ranger project by delivering four features and resolving two bugs over two months, focusing on backend reliability, security, and maintainability. Enhanced tag management by fixing delta sync and deduplication issues, ensuring accurate tag-based access control. Upgraded the codebase for Java 17 compatibility, modernized build tooling with Maven, and replaced deprecated Nashorn with GraalVM for improved JavaScript integration. Strengthened authentication by updating cryptographic components using Bouncy Castle and improved documentation for runtime configuration. Addressed test suite reliability by refining script evaluation and assertions, demonstrating expertise in Java, backend development, and test automation while collaborating across teams on security-critical improvements.
