Yes, absolutely. Even the biggest Fortune 500 companies hire interns and juniors to code in relatively complicated apps and systems. Sooner or later they hire more mid-to-senior level engineers to clean up the mess. That example isn't even bad, either. At least you can understand it by reading it. If you've never had to spend days deciphering an ouroboros of several nested loops and if-statements in 2000+ line functions in classes with multiple layers of inheritance written by someone(who has since left the company) with a lack of experience or talent, you are one lucky individual IMO.
