Practical SQL & Python
for real business questions
Learn how analysts actually work with vague requests, messy tables, and incomplete data.
WHAT THIS SITE IS ABOUT
Most data problems are not about advanced techniques. They are about asking better questions, pulling the right data, and slowing down long enough to understand what it is actually saying.
I share step-by-step breakdowns of real analytics problems so you can think clearly, write better queries, and explain results with confidence.
WHAT YOU’LL FIND HERE
SQL
Readable, maintainable queries designed for real datasets.
Python
Python as a way to explore and understand data, not just produce outputs.
Business Thinking
Clear framing before code so the analysis stays connected to the decision.
WHAT YOU WON’T FIND HERE
Machine Learning
No model-building tutorials. Just practical analytics under real-world constraints.
Advanced Statistics
No advanced statistics. Just enough to reason clearly about real data.
Pure Theory
No theory for its own sake. No abstract concepts without a practical application.
