Rockstar
Top expert inGeospatial Technology and Web Mapping
Even Rouault is an experienced French software engineer with 18 years specializing in back-end and geospatial open-source projects. As an independent developer based near Paris, he has a track record of hardening and modernizing critical libraries—GDAL, PROJ, PostGIS, MapServer and curl—fixing memory leaks, edge-case bugs, and improving CI and cross-architecture builds. His work spans low-level C/C++ robustness, database spatial logic and build automation, and he often couples bug fixes with test case additions to prevent regressions. A prolific contributor to the OSGeo ecosystem and to high-profile projects like curl and OSS-Fuzz, he blends deep domain expertise in coordinate transformations with pragmatic maintenance that keeps geospatial tooling production-ready.
