Why your previous developer was terrible

You hired a new developer for a project you’re working on and she seems to have solved all of your problems. She’s been on the job for 3 days and she’s already suggested upgrades for 5 of your libraries and re-organized your JIRA issues. At every turn, she seems to validate your choice in hiring her. She’s found 8 bugs that were glaring and would have caused a critical meltdown. How terrible was your previous developer that he couldn’t have spotted any of this??

This post rings true to what I’ve seen and brings up the great quote by Paul Butterworth:

“Where the heck were you when the page was blank?”
