Summary
🤩
Rockstar🎓
Top SchoolChangkun Ou is a Staff Engineer based in Munich with 12 years of experience bridging academia and production engineering, holding a PhD in Computer Science from LMU Munich and teaching as an external lecturer. He specializes in low-level systems and performance engineering—most notably contributing to the Go runtime and tooling (golang/go and related repositories) where his work on timers, stack management, garbage collection, and synchronization measurably improves performance and stability. At SIXT he progressed from software engineer to staff engineer, shipping backend and mobile build improvements while also contributing to cross-platform GUI work and modern C++ documentation. He combines rigorous research instincts with pragmatic engineering: optimizing memory and scheduling inside runtimes by day, exploring the intersection of science and art in his public projects by night.
