Worked on the BioKIC/Symbiota repository to deliver a targeted Leaflet map enhancement focused on persisting map controls and marker clusters for post-render manipulation. Using JavaScript, LeafletJS, and PHP, the developer encapsulated layer and scale controls, as well as marker clusters, within the map instance to support dynamic user-driven customization after initial rendering. This non-invasive approach maintained the integrity of core Symbiota code, reducing maintenance overhead and risk to existing functionality. The work improved user experience by enabling richer interactions and future flexibility, and collaboration was evident through co-authored commits and clear attribution in the project’s commit history.
