I am a Senior Director of Engineering at Meta/Facebook, where I have worked on AI, ASIC/GPU/Accelerator, LLM/Llama, hardware/software co-design, High Performance Computing (HPC), Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), databases, and more broadly, Meta's planetary-scale private cloud, which comprises millions of machines and offers capabilities similar to those of public clouds. Prior to Facebook, I was a research scientist and manager at IBM T.J. Watson Research Center.

My research publications might help shed some light on my past work. See the full list here or at Google Scholar.
