Summary
🤩
Rockstar🎓
Top SchoolPatrick Ziegler is a research-focused software engineer at Lehrstuhl FAPS in Erlangen with 11 years of experience bridging vehicle operating systems, intralogistics, and industrial image processing. He holds an M.Sc. in Mechanical Engineering from FAU and has applied that background to practical Siemens projects, including a master’s thesis building an adaptive vision system for quantifying carriers in production. Patrick contributes to significant open-source projects—maintaining polybar and improving GraalVM compiler code—demonstrating strength in backend refactoring, crash fixes, and performance-sensitive tooling. He combines academic rigor with hands-on deployment experience, moving from teaching robotics frameworks to shipping production-ready software for embedded and industrial contexts. A less obvious strength is his ability to translate low-level compiler and system changes into more maintainable codebases, making complex systems easier for teams to evolve.
