Rockstar🎓
Top SchoolOleksandr Kachan is a seasoned software engineer from Ukraine with six years of focused experience in C++ backend and build systems, currently contributing at Percona since 2020. He has deep practical expertise in compiler compatibility, CMake, and AddressSanitizer integration—skills honed through upstream contributions to the PerconaFT key-value store where he resolved GCC/ASAN build issues and improved third-party build integration. His background spans embedded AVR development, SIP and IVR systems in Python, and web/backend work with JavaScript and Perl, giving him a rare full-stack fluency across low-level systems and higher-level application logic. Former roles in automation QA and senior Python engineering reflect a strong testing mindset and automation-first approach to reliability. Colleagues rely on him to tame complex build chains and make brittle toolchains reproducible and warning-free across compiler versions.
