About DriveDataScience
Hi, I’m Naveen Vuppula — a Senior Data Engineering Consultant based in Ontario, Canada. I work with Azure, Databricks, Fabric, AWS, Python, SQL, and Snowflake daily. This blog is my way of teaching data engineering the way I wish I had learned it — through real-life analogies, production patterns, and hands-on code.
Every concept is explained like you are learning it for the first time. No jargon without context. No theory without practice. 100+ posts and growing.
