PROFILE

Sina Mahdavi

Over a three-month period, contributed to the Swift toolchain by enhancing dependency scanning and build reliability across multiple repositories, including mrousavy/swift and swiftlang/swift-build. Developed robust prefix and path remapping features using C++ and Swift, refactoring argument parsing and data structures to align with LLVM standards and support flexible mapping formats. Improved dependency validation in swiftlang/swift-build by adding support for modular includes, a new V2 trace format, and more resilient trace parsing with regular expressions and JSON decoding. Addressed build determinism and error handling by implementing deduplication in dependency collection and graceful processing of empty trace files.
