PROFILE
Gaelferrand
Gael Ferrand contributed to the MTES-MCT/trackdechets repository by delivering features and fixes that improved revision workflows, data validation, and observability. He overhauled the revision request process, unified revision states, and enhanced both backend and frontend logic to streamline user experience and compliance. Using TypeScript, GraphQL, and Docker, Gael implemented robust validation logic for waste intake forms, expanded test coverage for critical mutations, and set up a local observability stack with Prometheus and Grafana. His work emphasized code hygiene, test-driven development, and maintainability, resulting in a more reliable, scalable system that supports accurate reporting and efficient development cycles.
