Rockstar🎓
Top SchoolChris Sarbora is a Distinguished Engineer with 13 years of software experience, now at General Motors after leadership roles at Meta and Facebook where he drove low-level systems, XR input, and release-critical tooling. He blends deep systems and platform expertise—kernel drivers, JIT/AOT tuning, and on-device update architectures—with hands-on backend and build automation work evidenced by contributions to high-profile open-source projects like Facebook's Buck and Redex. Chris has a track record of solving hard performance and reliability problems at scale, from cutting crash noise and improving scroll performance to enabling reliable AR device updates under intermittent connectivity. He mentors engineers and codified C++ best practices adopted across thousands of developers, showing an ability to scale technical standards as well as teams. Comfortable across embedded, mobile, and cloud build systems, he also brings a curious background in photography and early-stage product engineering that informs pragmatic, user-focused technical decisions. Based in Spicewood, Texas, he combines production-grade systems thinking with a knack for refactoring and tooling that unlock developer velocity.

A fast build system that encourages the creation of small, reusable modules over a variety of platforms and languages.
Role in this project:Backend & Automation Engineer
Backend & Automation EngineerContributions:18 commits, 1 push in 2 years 11 months
Contributions summary:Chris's contributions primarily focused on improving the build system, Buck. They made significant changes to `TargetNode` visibility, introducing concepts like `withinView` and refining visibility patterns. Their work included refactoring Java code, specifically in the `JavaDepsFinder`, `ParsePipeline`, and associated tests, to operate on `TargetNodes`. They also made additions to the clang assembler command. These changes indicate involvement in both backend logic and the build automation aspects of the project.
