When I started doing frontend development, I was quite shocked with how people managed to cowboy code their way into building fully functional products with a decent paying client base.

I am talking about fully function SaaS with payment gateway and all, but no version control beyond full backup copies, and spaghetti code everywhere you can literally bring the website down trying to change the homepage design.

... and the startups that managed to do better, some of them forgot the .git on production exposing their entire source code *facepalm*
