Worked on the gdtk-uq/gdtk repository to enhance build configuration reliability and cross-platform consistency over a two-month period. Focused on improving configuration hygiene by standardizing dub.json formatting, which reduced parsing errors and deployment risks across different development and CI environments. Addressed a configuration bug by removing tab characters to ensure consistent JSON parsing. In the following month, implemented a portability enhancement in the Makefile by replacing echo with printf for generating buildinfo.json, ensuring correct handling of special characters and improving build process reliability. Utilized skills in build systems, shell scripting, and configuration management with JSON and Makefile technologies.
