Top SchoolEugene Zemtsov is a Senior Software Engineer in Redmond with 16 years of experience building robust media, debugging, and cloud infrastructure at Google, Microsoft, and prior firms. He currently works on Chrome’s Media and WebCodecs subsystems, pairing low-level video codec and bitstream expertise with practical testing across browsers. His open-source contributions include improving LLDB’s signal handling and GDB remote debugging and strengthening Chromium’s HEVC/H.264 parsers—work that reduces remote round-trips and hardens media pipelines. Comfortable across front-end and back-end domains, he has a track record of shipping production fixes and tests that prevent subtle failures in encoders, debuggers, and file systems. Trained as a computer engineer, he blends systems-level rigor with a knack for writing testable, maintainable code.
