One photo, two milestones! The golden badge marking 5 years of Day 1 with AWS and publishing my first book! It didn’t seem completely real until I received the print copies.

Data cleaning and engineering is often the unseen grunt work that lays the foundation of all machine learning and AI, especially critical for Generative AI foundation models. The book covers everything you need to collect, clean, and prepare data for pretraining, fine-tuning, and analytics on AWS using SageMaker, Glue, EMR, and more.

I hope you have as much fun reading this as I had writing it along with my very talented coauthors Navnit Shukla and Sankar Sundaram. Time flies fast when you are having fun — here’s to the next 5 years!
