About

I'm Tivon.

I spend my time translating business questions into answers, using SQL and Python to make sense of situations that are often ambiguous or unclear.

I’m a Market Research Specialist with an M.B.A. and M.S. in Business Analytics from the George Washington University. I also have a bachelor’s degree in accounting and spent over 10 years in finance and accounting before graduate school.

This combination of business context and numbers discipline is why I focus on definitions, validation checks, and making assumptions explicit before I trust a result.

Practical SQL & Python for real business questions

Most SQL and Python tutorials focus on syntax, not how analysts actually think.

In real analyst roles, the work doesn’t start with a clean dataset or perfectly defined question. It starts with vague requests, incomplete context, messy tables, and limited time.

Here, I focus on answering real business questions with data, step by step, using the kinds of information analysts actually have.

How I approach analytics

The goal isn’t perfect analysis. It’s analysis that’s good enough to support real decisions.

You won’t find machine learning, advanced statistics, or theory for its own sake here. Just practical analytics, grounded in real-world constraints.

Why this site exists

This site is a working notebook. It’s where I document how I think through business problems, deepen my understanding of SQL and Python, and share patterns and ideas that hold up outside of textbooks. Writing things out forces clarity, which is what good analysis depends on.
