Tyler Calder

I’m a software engineer. I learned to program while doing analyst work while earning my economics degree. After graduating I worked as an data analyst for a short while, but realized I really loved programming and building software. Since then I have worked in various roles, including designing and building the backend for GameUp, a business I started. I enjoy studying programming and software engineering, and write about them here on this blog.

Below is a quick summary of my work background, A more formal resume can be made available upon request.
