Worked on backend stability for the facebookresearch/momentum repository, focusing on improving compile and export workflows using PyTorch and Python. Addressed a critical bug by implementing a fallback mechanism to the Torch backend during compilation and export, ensuring correct kernel selection and traceability. Introduced a conditional check with torch.compiler.is_compiling() before accessing context variables, which prevented Dynamo capture errors and stabilized backend resolution paths. This solution reduced failures in export tests and aligned the workflow with CARMM ExecuTorch export requirements. The work demonstrated strong backend development and unit testing skills, contributing to more reliable and maintainable export and compile processes.
