Worked on stabilizing the LZ4 encoding path in the hyrise/hyrise repository, focusing on improving reliability and reducing crash risk in encoding workflows. Addressed a segmentation fault by refining how string offsets are stored, ensuring only non-zero lengths are handled, which prevents errors during dictionary creation with zstd. Introduced ASAN-enabled stability tests to validate encoding behavior under edge cases, exposing issues present on the master branch and strengthening regression protection. Collaborated closely with peers to enhance code quality and review processes. Utilized C++ for development, debugging, and software testing, contributing to more robust and maintainable data encoding infrastructure.
