During February 2026, Imaolo focused on stabilizing the Metal backend in the tinygrad/tinygrad repository by addressing a memory management issue that caused Metal buffers to persist after deallocation. Using Objective-C and Python, Imaolo updated the MetalAllocator to explicitly call release() on underlying Metal buffers, ensuring proper resource cleanup. To prevent regressions, Imaolo introduced a targeted unit test that verifies correct buffer deallocation, improving the reliability of tensor operations on GPU hardware. This work demonstrated depth in backend development, GPU programming, and test-driven development, resulting in a more robust Metal backend and enhanced memory management for the project’s users.
