Musician, Scientist, Educator

Computer Scientist

Programming has been a part of my life since I was about 6 years old after learning about viruses and trying to understand how video games were made. From there on I got into game development and software, eventually working my way up to scripting, web development, and app development soon after. Over time, I have come to learn and utilize over 50 different programming languages, across all platforms and in various environments. Since then, I have developed numerous pieces of software and published many research papers in computer science, alongside a few textbooks and other educational materials.

I also currently teach all the computer science courses at Craig High School in Janesville, WI, including AP Computer Science Principles, AP Computer Science A, Data Structures/Algorithms (Java), Web Development, Game Design (Godot), and Computer Programming I/II (Python/Adv. Python and C#) — as well as a few various online college-level courses. I have also worked as a webmaster, researcher, and senior software engineer, and currently do freelance graphic, web, app, and software design under my business Zero Development, which also hosts my portfolio of programs, research, and designs.
