PROFILE

Joe Todd

Over five months, contributed to modular/modular and modularml/mojo by building high-performance, distributed GPU computing features focused on scalable tensor operations and robust benchmarking. Leveraged Python, Mojo, and YAML to modernize GPU kernels, unify APIs, and optimize matrix multiplication and reduction workflows for multi-GPU environments. Enhanced memory management and test reliability by migrating to new tensor abstractions and improving race condition handling. Developed comprehensive benchmarking and performance regression tooling, including multi-GPU smoke tests and communication benchmarks, while expanding documentation and technical writing. Addressed bugs in memory allocation and coordinate transformations, resulting in safer, more reliable distributed computing and streamlined performance validation.
