I started as an intern at a big company (
Fahad Khan) with hundreds of php files as an internship. My first recommendation was to do half it MVC-friendly and reduce lost files, bugs, etc.
I overdrive 3 months, my internship is gone and they're doing me a low-pay job, I've been staying 6 months longer and completing the other half and doing some more work. I have resumed a mediocre job that took 5 years in 9 months at the end of this period (9 months). I know on my pocket I got them. I know.
