Hey! I'm Cristian Gonzalez, I created SQL Easy while I was working at StubHub (an eBay company) to help me and my workmates learn SQL easily and fast.
The idea was to create something that could be used with a hands-on approach to learning, meaning students must interact with the SQL interpreter in order to adapt and learn.
I created this website in the fall of 2017, and since then more than 80,000 students finished the tutorial SQL.
This project was based on this repository (License).
Hope you learnt something.
