During May 2025, Dauphinsss contributed to the Redibo-Frontend repository by developing a personalized GPS radius-based map filtering feature, enabling users to view only vehicles within a selectable distance from a chosen location. This functionality relied on haversine distance calculations and dynamic radius editing, enhancing geospatial filtering for end users. Dauphinsss addressed mobile usability by adjusting the map component’s height to 95 percent, ensuring reliable rendering on small screens. The work demonstrated practical application of React, TypeScript, and Leaflet, with targeted commits that improved both maintainability and user experience. The scope was focused, delivering one feature and one bug fix.
