Sahir Karani

I'm a software engineer based in New York City with deep expertise in full-stack development and artificial intelligence. At Amazon Prime Video, I architect ML-powered personalization and recommendation systems at scale, building the intelligent infrastructure that helps millions of viewers discover content they love.

A graduate of NYU Tandon School of Engineering with a focus on Computer Science and Cyber Security, I've built my career solving complex problems at scale. I'm passionate about using technology to make a meaningful impact.

Outside of work, you'll find me chasing finish lines, whether it's running marathons, competing in Spartan races, or diving for volleyballs on the court. Endurance sports and team competition keep me balanced and driven.
