The Data Science Tutor

Data science, SQL, and data skills made simple — so they finally click.

If you're trying to break into data and every tutorial feels like it was written for people who already know the basics, you're in the right place.

I'm Will, a working data professional, and I teach SQL, databases, and data fundamentals with simple analogies first, then the actual code.

Every lesson uses the fictional company Bean There Coffee Co., so you learn one database instead of starting over with random examples. Grab the free practice database and follow along.

What you'll learn:
• Data science fundamentals
• Dirty vs. clean data
• Primary keys, foreign keys, and relationships
• SQL JOINs: INNER, LEFT, RIGHT, FULL OUTER, CROSS, and SELF
• GROUP BY, CTEs, window functions, UNIONs, and more
• Data visualization, analytics, and BI

New lessons Tuesdays. Shorts Thursdays and Saturdays.

Learn SQL. Understand data. Build real-world skills.

Clean data, clear mind.
