Jean-Marc Viglino enhanced the IGNF/geopf-extensions-openlayers repository by architecting advanced geospatial search features and delivering a major upgrade to parcel search workflows. Over two months, he developed a robust search subsystem with autocomplete, multisearch, and geocoding integration, focusing on accessibility, error handling, and strict input validation for postal and INSEE codes. Using JavaScript, React, and OpenLayers, he improved keyboard navigation, responsive data fetching, and municipality data formatting, while enforcing design constraints and accessibility standards. His work addressed reliability and data integrity, laying a scalable foundation for geolocation-enabled workflows and improving the overall maintainability of the codebase.
