Summary
🤩
RockstarSebastien Peillet is a software engineer with 10 years of experience specializing in geospatial systems and tooling, currently contributing at Hytech Imaging. Trained as a géomaticien (master SIGMA), he blends domain expertise in GIS with practical C++ backend development, notably improving QGIS core features for map theme management and fixing geometry handling in GPKG. He is comfortable working deep in native code to manage complex state (expanded/collapsed and visibility of layer groups) and resolving subtle spatial data bugs. Quietly practical, he connects geospatial theory to production-grade engineering, making mapping workflows more reliable and reproducible.

Contributions summary:Peillet contributed to the QGIS codebase by implementing and refining features related to map theme management and display. They added functionality to store and restore visibility states of group nodes within map themes, specifically improving handling of embedded layers. These changes involved modifications to core C++ code, including the `qgsmapthemecollection.cpp` and `qgsmapthemecollection.h` files, to manage expanded/collapsed and checked/unchecked states of groups and layers. Furthermore, the user addressed a bug related to adding vertices in CompoundCurveZ geometries within the gpkg format.
