About

I'm a software engineer specializing in ML platforms and infrastructure. Currently leading MLOps and infra initiatives at Turing, where a three-person platform team builds and operates 1,000+ GPUs of Slurm-based training infrastructure across AWS, GCP, and on-prem to accelerate autonomous-driving research.

Before Turing, I worked across SRE at Splunk (Cisco), ML platform engineering at Preferred Networks on MATLANTIS, customer engineering at Google Cloud, and backend / SRE / security engineering at Recruit and NTT Communications.
