Five years writing SQL, designing experiments, and shipping dashboards inside India's fastest consumer companies.

This site is the curriculum I wish existed when I was starting out: structured, opinionated, and built from real patterns I’ve seen in production at scale.

The roadmap, articles, and resources are free. QueryLab, the SQL practice product, is where the paid side of the site lives, real queries, graded on the spot, with Sprint Coins as the currency for hints and full solutions. If any of it helps you, the best thing you can do is share it with someone who’s trying to break into analytics.
