PROFILE
Zibi Sarbinowski
Worked across llvm/clangir, intel/llvm, and swiftlang/llvm-project repositories to improve cross-platform reliability and maintainability in C++ codebases. Focused on stabilizing test suites for IBM z/OS by introducing platform-specific test expectations, which reduced false CI failures and improved build consistency. Applied targeted code refactoring in the intel/llvm locale headers, removing unused declarations to streamline future maintenance without altering functionality. Addressed z/OS compatibility in swiftlang/llvm-project by exposing strnlen() and updating string length handling, ensuring successful builds on that platform. Demonstrated strengths in build systems, code refactoring, and cross-platform development, with a focus on traceable, audit-friendly engineering practices.
