Worked on the iree-org/iree repository to enhance compiler stability and memory safety within the pass pipeline. Focused on improving the HoistIntoGlobalsPass by addressing a double-free issue, the work involved deferring the removal of dead operations to a later pass, which reduced the risk of memory corruption during large builds. This targeted bug fix improved the reliability of global hoisting and supported smoother optimization passes in production environments. Leveraged expertise in C++ for compiler development, memory management, and pass optimization, demonstrating a methodical approach to maintaining robust code and ensuring safer, more predictable compiler behavior in complex workflows.
