Data Analytics Online Tutoring: Master Power BI, SQL, and Python for Abitur and University Success

Hi, I'm Gavin. I work in data analytics — Power BI, SQL, Python, Databricks — and I've spent the last few years building reporting systems and teaching people how to use them across nine countries. I'm here because I genuinely enjoy both sides: solving the technical problem, and helping someone else understand it well enough to solve it themselves. How I work: I start with the question, not the tool. Before we open Power BI or write a query, we'll figure out what decision you're trying to support and why it matters. Then we build. I'd rather you understand one thing deeply than half-learn five. What you can expect from me: Clear explanations, no jargon for the sake of it, and patience with any question — including the ones you think are too basic. I'll push you to try things before I show you the answer, because that's how it sticks. And I'll tell you honestly when something is confusing, because pretending otherwise wastes your time. What I'll expect from you: Curiosity, and a willingness to get things wrong in front of others. Mistakes are how this works. Looking forward to it.
