PROFILE

Abdurrahman Akkas

Over six months, contributed to the pytorch/executorch and pytorch/ao repositories by building and refining backend features focused on graph optimization, quantization, and extensible output APIs. Leveraging C++, Python, and PyTorch, implemented targeted performance improvements such as removing redundant tensor operations and generalizing permute fusion to streamline neural network execution. Enhanced API flexibility by enabling configurable output targets and improved quantization reliability through robust metadata propagation. Addressed critical bugs in tensor operation correctness, memory safety, and numerical accuracy, including fixes for dtype validation and out-of-bounds writes. Maintained strong test coverage and documentation to ensure maintainability and deployment stability throughout.

Work History

April 2026

3 Commits

Apr 1, 2026

April 2026 (2026-04) focused on stability and correctness improvements in Executorch. No new user-facing features were released this month; the priority was addressing correctness, memory safety, and numerical accuracy across core tensor ops. The work reduced risk of incorrect dtype handling, improved pooling divisor logic, and safeguarded batched SVD indexing, yielding more reliable model training and inference.
