PROFILE
Shivam Raikundalia
Sraikund worked extensively on profiling and memory visualization tooling in the pytorch/pytorch repository, building features that enhanced GPU memory observability, profiling accuracy, and developer onboarding. Over eight months, Sraikund delivered robust improvements to the profiler’s concurrency, memory snapshot reliability, and CUDA memory instrumentation, using C++, Python, and JavaScript. Their work included integrating Kineto submodule updates, adding user-scoped profiling, and expanding documentation for profiling APIs. By upgrading the MemoryViz.js visualizer with D3.js and improving event handling, Sraikund enabled more interactive and reliable memory analysis. The engineering demonstrated depth in system programming, data visualization, and performance optimization across backend and frontend components.
