During March 2025, Jlin focused on enhancing the user interface and experience for the Racehub repositories, Jfranbm04/racehub and Jfranccbm04/racehub. He implemented global CSS styling and transitions to unify the look and feel across main and authentication screens, while introducing dynamic header backgrounds to highlight event themes and increase engagement. Using JavaScript and HTML, he resolved icon rendering issues for running and cycling sports, ensuring accurate visual representation. Jlin also improved dependency management by aligning composer.lock files for stability. His work demonstrated a thoughtful approach to frontend development, balancing visual polish with maintainability and addressing both user and technical needs.
