Summary
🤩
Rockstar🎓
Top SchoolFelix Obermaier is a Software Architect with 16 years of experience building GIS-driven applications and macroscopic traffic demand simulation models at Ingenieurgruppe IVV in Aachen. Trained as a civil engineer at the Technical University of Munich, he combines domain expertise in transportation with deep hands-on skills in spatial libraries like SharpMap and DotSpatial. Felix is an active open-source contributor to widely used geometry toolkits (JTS and NetTopologySuite), where he has fixed parsing and geometry-normalization bugs, implemented distance algorithms, and strengthened test coverage. He excels at turning complex spatial problems into robust backend solutions and brings a pragmatic eye for edge cases that frequently surface in real-world traffic data.

The JTS Topology Suite is a Java library for creating and manipulating vector geometry.
Role in this project:Back-end Developer
Back-end DeveloperContributions:1 review, 19 commits, 33 PRs in 4 years 2 months
Contributions summary:Felix primarily contributed to the JTS Topology Suite, a Java library for geometric algorithms. Their work focused on fixing bugs related to parsing whole numbers in the `DD.parse` method and ensuring the `Polygon.normalize()` function worked correctly with `CoordinateSequence` objects. Additionally, the user refactored and added utility methods, corrected existing code, and improved the codebase by adding comprehensive unit tests to enhance its robustness and reliability.
