Rockstar🎓
Top SchoolKamil Rytarowski is a pragmatic technology leader and Chief Technology Officer with 14 years of hands-on experience building and porting low-level systems across Unix-like OSes, currently leading the engineering team at Moritz Systems. He is a widely recognized open-source maintainer and NetBSD expert, responsible for hundreds of contributions that brought NetBSD support to major projects such as CoreRT, LLVM/Clang/LLDB, Mono, libuv, and kernel fuzzers like syzkaller. Kamil’s work spans compiler internals, runtime porting, sanitizers, and kernel/userland tooling—skills honed during a prior contracted developer role with NetBSD and embedded systems work on ARM platforms. He combines systems-level C/C++ mastery with pragmatic QA and test automation practices to improve portability and reliability across platforms. An occasional conference speaker and published author in IT press, he pairs deep technical curiosity with a talent for making complex platform-specific issues legible and fixable for broader developer communities.
