Worked on the JetBrainsRuntime repository to enhance cross-platform reliability by refining low-level runtime systems using C++ and Java. Focused on removing obsolete synchronization flags, ensuring that synchronization logic is consistently applied and reducing dead code. Addressed CPU instruction set variability by implementing a fallback for SSE4.2 intrinsics, which included disabling unsupported instructions, emitting warnings, and expanding test coverage to verify correct behavior. Applied code refactoring and compiler optimization techniques to stabilize critical code paths. These efforts improved platform resilience and maintainability, while comprehensive testing reinforced the reliability of low-level features across diverse hardware environments and runtime configurations.
