I am very happy with our experience so far with Varsity Tutors. They matched my daughter with reading specialist Mary and she is wonderful! My 10 year old daughter feels happy after her sessions and believes her tutor has already helped her.

Thomas: Wheeling tutor

Certified Tutor

I spend entirely too much time working on computer related projects and could use an intervention, possibly involving a lobotomy. I suspect I am ADD patient zero. Asimov's Robot stories led me to a life-long interest and PhD in artificial intelligence from Northwestern University.

I have worked for Lucent Technologies, Microsoft, Citrix Labs, and Ernst & Young in numerous areas: telecommunications, distributed processing, databases, data science and machine learning to name a few.

I am an expert in C, C++, C#, and Java coding. I am proficient in Python, SQL, and a number of other languages.

I taught upperclass and graduate computer science topics at Illinois State University for six years, including operating systems, distributed processing, graphics, and gaming. I also taught at DigiPen Technical Institute for a year, topics including software engineering and artificial intelligence.

I also do android apps for games and open science projects.

I have collaborated on a robot of a wormlike creature that is on display currently at Ars Electronica in Linz Austria.

See https://github.com/portegys and tom.portegys.com/programs.html for code projects.

See tom.portegys.com/research.html for a list of my publications in AI and other fields. My most recent project is an AI simulation of honey bee nectar gathering, which includes a fascinating dance they do to tell other bees where the nectar is outside the hive.

I enjoy the teaching part of tutoring quite a bit. Grading homework not so much! Last summer my granddaughter and I built a horse racing game with Godot, for example. My approach is to build things as the best way to learn. Computers give you that opportunity!
