Being able to solve 80% of AoC is nothing to sneeze at. There are plenty of roles that are open to you. You should start applying to jobs that interest you. If you have no other experience you can point to, I'd take one or two of last year's AoC puzzles you solved and write a short write-up on how you solved it. Explain the problem, explain why it's hard (it's a challenge after all), talk about failed attempts (this is important), and talk about how you solved it. I'd include this with your resume or cover letter. Remember, the goal is to get to the next stage of the interview process - so you want to give them something to signal you're worth interviewing. AoC (or open source work) gives the interviewer something to ask about.
