PROFILE
Andrea Gueugnaut
Andrea Gueugnaut led the engineering and delivery of end-to-end housing data and document management features for the MTES-MCT/zero-logement-vacant repository. Over 17 months, Andrea architected and implemented robust backend APIs, event-driven data models, and scalable frontend workflows using TypeScript, React, and Node.js. The work included building document upload and preview flows, integrating AWS S3 for storage, and designing schema-validated payloads to ensure data integrity. Andrea’s approach emphasized test-driven development, accessibility, and maintainable code, resulting in reliable housing-owner workflows, granular event tracking, and improved user experience. The depth of work enabled safer deployments and streamlined housing operations at scale.

Dec 1, 2024December 2024 delivered a substantial frontend UX overhaul, backend/data modeling refinements, and broader CI/CD coverage across MTES-MCT/zero-logement-vacant. Key UX changes include a MUI Autocomplete-based establishments search, enhanced selection components, onboarding modal on authenticated pages, and DSFR theme improvements. Security and quality improvements were achieved through a 12-character password policy, test/test stability fixes, and code coverage expansion across all packages. Data reliability and performance were boosted by refined establishment data modeling, intercommunalities filtering, and improved seeds. UI components for housing and campaign tables were refactored for reuse with TanStack Table, and new data-import tooling streamlined operations. All of these changes increase business value by reducing user friction, improving data quality, and increasing confidence in deployments.
