During June 2025, contributed to the JetBrainsRuntime repository by delivering a key architectural refactor focused on garbage collection virtual machine operations. The work involved reorganizing GC-related VM operations in C++ by introducing new base classes, VM_Heap_Sync_Operation and VM_GC_Collect_Operation, and implementing the is_gc_operation() method to improve categorization and handling of these operations. This refactor enhanced the maintainability of the codebase and established a clearer hierarchy for future garbage collection enhancements. The approach demonstrated strong skills in code refactoring, garbage collection concepts, and VM operations, with an emphasis on building a foundation for scalable and organized future development.
