Hi, I'm Purak Jain, an applied scientist.
I research and build multi-agent AI systems, currently working on multi-agent coordination, continual learning memory, and RL-ready evaluation sandboxes for AWS DevOps Agent with a team of scientists I lead across Seattle, San Francisco, and New York. Before that, I spent 8 years in Amazon Advertising building bidding algorithms, incrementality measurement, and recommender systems that optimized over $1B in global ad spend across Google, Meta, and YouTube.
I write here about things I am learning.
