I’m sorry I don’t know how to help, but I thought I’d share my experience. I have the literal opposite problem, and have been struggling just as hard with keeping a job.
I’m so focused on trying to keep clean and maintainable code that I end up struggling to get things done quickly. I could try to work harder in a less structured manner, but I end up loosing track of what’s going on, and I start stressing out about the lack of code cleanliness, which always makes me to work slower, and then it doesn’t look like I can get things done.
Anyway, I know of some people in InfoSec that are able to get along fine with “just scripting,” so perhaps it would be a good alternative for you. Another idea is that you could try working for a young startup—they’re more focused on making prototypes quickly than they are making them stable and maintainable, so maybe that could work in your favor.
