SQL/Math Tutor

Toni V.

I’ve been spending more time helping people learn SQL in a practical, real-world way.

A lot of learners struggle with SQL not because it’s hard, but because most practice problems don’t reflect how data is actually used in real jobs.

So I’ve been focusing on:

Writing queries from scratch
JOINs, aggregations, window functions
Working through messy, realistic datasets
Interview-style SQL practice

My background is in healthcare data and analytics, where SQL is used daily across claims and operational reporting.

If you’re trying to get more comfortable with SQL or break into analytics, I’m open to a few tutoring sessions—feel free to reach out.
