SOFTWARE ENGINEER

Development Logs

Sigmafox COSY Interpreter

A language interpreter used in beam physics.

BACKGROUND

My name is Chris and I am a software engineer with over a decade of experience in programming and development. I have a Bachelor's degree in Computer Science at Northern Illinois University and I specialized in computational software and minored in computational mathematics.

While I spend most of development time in C and C++, I also develop in Python, Rust, and C#. I am also a capable full-stack developer with experience using a variety of popular web frameworks. Many of personal projects center around low-level programming in computer graphics and compilers, but I am known to venture into the world of front-end development for the love of the game.

As of May 2025, I am looking for a new role as a software engineer. If you're a recruiter and want to reach out, please visit my linkedin page.
