Loïc Guillois developed the Vacancy Analysis Feature for the MTES-MCT/zero-logement-vacant repository, focusing on enhancing vacancy monitoring and analysis for stakeholders. He extended the dashboard data model to support different analysis types and updated frontend routing to provide seamless access to new analytics views. Using React, TypeScript, and SCSS, Loïc integrated dedicated routes and navigation items, allowing users to efficiently track and evaluate vacancy trends. The work centered on feature delivery and integration with existing dashboards, laying a foundation for future reporting improvements. Over the month, Loïc concentrated on robust feature implementation rather than bug fixes, demonstrating depth in frontend development.
