During December 2024, Sebastian worked on the pablo-icm/emm repository, focusing on author avatar asset maintenance. He refreshed and standardized avatar images for four author profiles by removing outdated files and adding updated assets, ensuring consistent and accurate profile visuals. Using Git for version control, Sebastian executed 14 commits with a clear add/delete pattern, which improved traceability and reduced the risk of broken image references. His work involved asset management and cross-author coordination, supporting faster UI rendering and enhanced branding cohesion. The project primarily utilized Git, image asset workflows, and repository hygiene, resulting in improved user experience and maintainable author pages.
