Worked on the mariadb-corporation/mariadb-columnstore-engine and mariadb-corporation/mariadb-docs repositories, focusing on build system stability and documentation accuracy. Addressed a critical build configuration issue by updating CMake scripts to ensure SELinux policy development files were correctly included and RPM dependencies resolved, aligning with MariaDB server’s build logic for improved packaging reliability. In parallel, updated the MariaDB Platform Deprecation Policy documentation using Markdown, clarifying platform support timelines and enhancing lifecycle guidance for users. Demonstrated expertise in CMake, Linux administration, and technical writing, delivering targeted improvements that reduced support ambiguity and increased the reproducibility and resilience of MariaDB’s build and release processes.
