PROFILE

Jan Lesage

Jan Lesage contributed to the Informatievlaanderen/association-registry repository by delivering robust API features for membership and association management, focusing on data quality, security, and maintainability. Over two months, Jan implemented public-detail membership changes, expanded region-based data support, and introduced deduplication workflows for associations. The work involved extensive use of C#, ASP.NET Core, and domain-driven design, with careful attention to test-driven development and CI/CD integration. Jan refactored address synchronization to a command-driven model, improved validation and authorization, and enhanced test infrastructure. These efforts resulted in more flexible APIs, improved data integrity, and a stable, well-tested backend architecture for the platform.
