"I'm a gentle geek, a Physics Ph.D. from UC Berkeley. I can handle most anything you throw at me in my areas of competence, so I can help you effectively & painlessly.

If I can't help you, you get your money back, even for Instant Book.

I have 3 areas of expertise:

1. MATH

* 15 years of tutoring algebra through calculus, and preparing for the math sections of the SAT, ACT, and GRE.

2. SOFTWARE

* I teach complete courses on SQL, including joins, subqueries, and window functions. I have 4 database servers: MySQL, PostgreSQL, SQL Server & Oracle. I have several SQLite sample databases, and in 5 minutes, I can get you practicing SQL on SQLite on your computer.

* I’ve used Python extensively, including web scraping (with Selenium) and working with the database types listed above. Sorry, no Data Science or Pandas.

* Linux, Bash scripting, awk, sed, grep & regular expressions.

* I've done many insane things with Microsoft Excel and VBA.

3. PHYSICS

* Ph.D. Need I say more?

I've been told I'm great at communicating with people at any level of understanding. I'll put you at ease, and happy to work at your pace, I love helping people. I have 10 years of experience as a software support engineer working through tough problems with people who started out upset & ended up happy & laughing.

Here's how many hours I've tutored in the most popular topics on Wyzant.com:

Python: 1,908

SQL & Databases: 1,694

For regular or Instant Book sessions, I charge only for the time used.

If you postpone or cancel regular or Instant Book sessions nicely, I'll void the charge. if you're not nice or blow me off, I may charge 100%." less...
