I am a Drupal developer. Or more specifically, I am a Drupal 7 developer *today* because my main client is on a D7 distro that isn't switching to D8 in the next two years. There simply is no budget.
I'm not sure what I will be tomorrow, or next month, or next year. I think I will bill myself as a Web Developer once again since I find myself building and iterating features on sites on a variety of publishing tools.
