Rockstar🎓
Top SchoolSimon Gottlieb is a Berlin-based software engineer with 11 years of experience building robotics and autonomous-vehicle software, and a track record of hands-on contributions to C++ open-source projects. He has worked on humanoid-robot soccer teams and self-driving car stacks, and for the past several years he’s freelanced on humanoid robotics—blending embedded systems, perception, and control. Simon’s open-source work includes precision-focused fixes to the widely used yaml-cpp library and practical tooling improvements to cppman, showing attention to numerical correctness and cross-platform robustness. His background in computer science with a bioinformatics minor gives him a measured, analytical approach to complex engineering problems and a penchant for low-level, correctness-driven code.

Contributions summary:Simon's primary contributions involved enhancing the `yaml-cpp` library's precision and locale handling for floating-point number representation. They fixed a critical bug by improving the accuracy of floating-point conversions. The user also ensured the library correctly parses files with carriage return line endings, and further improved the library by introducing a `FpToString` function to print floating-point numbers with a focus on providing a more accurate string representation of the float values.
