Worked on the apache/kudu repository to enhance webserver security and reliability by implementing TLS 1.3 support and addressing initialization issues in cluster management. Developed new functionality in C and C++ to introduce a configurable TLS 1.3 ciphersuites option, updated the minimum protocol version, and created comprehensive tests to validate secure communications. Improved the ExternalMiniCluster component by refactoring member initialization into the constructor’s initializer list, ensuring consistent startup behavior and code correctness. Focused on network security and robust software development practices, the work included updating regression tests to reduce future risk and contributed to safer, more stable cluster deployments and upgrades.
