Overview

I've spent 17 years on ML infrastructure - first at Cognizant, now at Summit AI. Cut p99 latency on the ML platform services from 424ms to 169ms. Reduced cloud spend on ML platform by 39% in two quarters. Before that: Amazon and Hindustan Unilever. Most at home with feature stores and model serving. Volunteer coding coach for school students.
