Worked on build system and package management improvements across the easybuilders/easybuild-easyblocks and easybuilders/easybuild-easyconfigs repositories using Python. Addressed a bug in the Miniconda Sanity Check by updating anaconda.py to remove the obsolete 2to3 executable from expected binaries, ensuring the sanity check accurately reflects current Miniconda3 distributions and reducing false positives in CI. Delivered a feature by removing legacy unixODBC 2.3.12 support from easybuild-easyconfigs, streamlining dependency management and reducing maintenance overhead. Demonstrated skills in system administration, precise repository updates, and commit-based traceability, with a focus on improving build reproducibility and clarity for downstream users.
