Thibaud Colas contributed targeted improvements across two open source projects over a two-month period. On django/djangoproject.com, Thibaud updated the fundraising target display by increasing the GOAL_AMOUNT constant, clarifying campaign goals for donors and aligning the site with current fundraising objectives. This backend change was delivered as a focused, auditable Python commit, minimizing deployment risk and supporting maintainability. In bigskysoftware/htmx, Thibaud addressed a UI bug affecting dark mode by updating button background styles using CSS, ensuring text visibility and consistent user experience across themes. The work demonstrated careful attention to both backend logic and front end accessibility concerns.
