About

Hi! I’m Rohan. I recently graduated with a BS in Computer Science from UCLA, and work as a software engineer. I’m originally from San Jose, California.

Work

I currently work at Facebook AI on enabling large-scale distributed training within the PyTorch framework. I’ve recently been working on helping build out model parallelism support within PyTorch, as well as investigating the scalability of data parallel training.

Previously, I’ve worked on building mortgage lending products at Blend, risk models at Affirm, and messaging applications for sports teams at Hudl.
