All projects that I work on outside of my employer's time are fully open sourced under the MIT license. Many projects that I work for as part of my work at Campbell Marketing and Communications are proprietary and closed source unless otherwise indicated..
If you are interested in contributing to a project I run, the easiest way is to read the CONTRIBUTING.md file within the project repository and hit the ground running. You can also contact me via the methods on the Contact page.
