Worked on cross-language enhancements for the eclipse-zenoh/zenoh-java and eclipse-zenoh/zenoh-kotlin repositories, focusing on precise entity identification and build reliability. Introduced the EntityGlobalId type to improve replier differentiation within Zenoh peers, updating data structures and JNI callbacks in both Java and Kotlin codebases. Synchronized dependency lockfiles using Cargo to ensure consistent builds across multi-language repositories, and updated dependencies to maintain current library versions. Leveraged skills in Rust, Kotlin, and system programming to deliver features that enable more accurate query responses and predictable integration workflows, demonstrating a methodical approach to dependency management and cross-language API design within distributed systems.
