PROFILE
Ahmed Henawey
Worked on the dart-lang/native repository to address a critical memory management issue involving Objective-C and Dart interoperability. Focused on fixing a garbage collection safepoint crash in ObjCProtocolBuilder by ensuring Objective-C blocks are properly retained during non-leaf FFI calls. Utilized Dart and Objective-C, applying expertise in FFI, garbage collection, and native development to strengthen block retention and lifecycle handling across language boundaries. Added targeted tests to verify stability and refined method implementations to improve memory safety. These changes reduced crash risk in mixed-language scenarios, enhanced cross-language interop reliability, and contributed to more robust native integration for production environments.
