Summary
🤩
Rockstar🎓
Top SchoolJonas Toth is a Senior Software Entwickler with 11 years of experience specializing in Embedded Linux and IIoT development using C++, currently working at IVU Traffic Technologies and contributing to static analysis at the LLVM Foundation. He combines deep compiler and tooling expertise—evidenced by notable contributions to clang and clang-tidy checks—with hands-on operational responsibility for running and automating complex embedded systems. A pragmatic engineer, he prioritizes well-structured development processes, thorough testing, and CI/CD automation across systems like GitLab CI, GitHub Actions, Jenkins and more. Jonas runs a personal homelab and customizes Gentoo Linux, reflecting a strong systems and Linux administration background beyond his professional roles. His work on clang-tidy and clang shows an ability to modernize large C++ codebases while carefully assessing which changes preserve behavior versus introduce risk. Based in Leipzig, he brings a blend of compiler-level insight and practical production experience to embedded software challenges.
