Summary
🤩
Rockstar🎓
Top SchoolBoris Zbarsky is a software engineer with six years of industry experience and a deep background in systems-level engineering from long tenures at Mozilla and currently at Apple. He combines rigorous academic training in mathematics and physics from MIT and doctoral-level study in mathematics at the University of Chicago with practical expertise in back-end and embedded systems. At Apple he continues to apply low-level platform knowledge, and his open-source work on the widely used Matter (project-chip/connectedhomeip) shows attention to platform-specific details, CI robustness, and cross-platform build configuration. Former roles at Mozilla, rising to Distinguished Engineer, reflect a history of technical leadership in browser and systems software. Based in Needham, Massachusetts, he brings a rare blend of academic depth and hands-on engineering that excels at fixing subtle platform issues and improving developer tooling. Colleagues know him for tackling deprecation and build fragility problems that quietly keep large projects shipping.
