Thibaud Colas contributed targeted improvements across two open source projects, focusing on both backend and frontend development. For django/djangoproject.com, Thibaud updated the fundraising target display by adjusting the GOAL_AMOUNT constant, ensuring the website accurately reflected new campaign goals. This backend change was implemented as a single, auditable Python commit, minimizing deployment risk while improving donor messaging. In bigskysoftware/htmx, Thibaud addressed a UI bug affecting dark mode by updating CSS for the hx-indicator demo, changing the button background to maintain text visibility. The work demonstrated careful attention to accessibility, code quality, and alignment with project requirements within a short timeframe.
