Use an enum to add roles to your User model
In 2022 we were hiring for senior Rails developers. I always require that candidates provide their GitHub username so I can browse through their public repositories, issues they wrote, and pull requests to open source repositories. Real senior developers occasionally find a handful of bugs or missing features in third party components and fix it right away. And since GitHub is still home to most open source projects, your contributions to the community are to be found there. At the very least, you should have some interesting pet project up there.
