Yury Delendik
Worked on the mozilla/gecko-dev repository to enhance WebAssembly runtime stability, focusing on memory management and garbage collection. Delivered features that improved memory handling, including fixes for boolean conversion and out-of-memory propagation in C++, and expanded WebPlatform Test coverage for memory-related scenarios. Refined suspendable stack tracing logic in both WasmPI.cpp and WasmPI.h, enabling more reliable garbage collection diagnostics and debugging. Integrated JavaScript debugging and advanced test configuration to ensure robust validation of new features. The work emphasized runtime reliability and maintainability, supporting cross-platform stability and more effective performance analysis in large-scale JavaScript and WebAssembly environments.
