Senior Freelance Tables Developer

Avid technologist that loves programming. An expert in requirements gathering, solution design, and implementation delivery, with significant experience in ‘triple-A’ video games on massive, distributed Agile teams, and with scalable Enterprise software development. Programming has always been my passion, starting with Lego Technic at the age of 7. I began creating my own text-based games in C, at the age of 10. I started web development at 13 (HTML, JavaScript, PHP), followed by Half-life and Unreal mod development. I continued working on a diverse array of personal programming projects throughout my 20’s while working for EA/BioWare, formalizing my experience as a ‘Professional’ programmer in 2017 with the University of Alberta. No longer working 60-80 hour weeks, I began freelancing as an Unreal Engine C++ programmer shortly after.
