I worked on a web project a few years ago. I've refactored a large part of the architecture, added repositories to the business layer, implemented inversion of control and dependency injection etc. (took me 2 weeks).

There was a second developer in the project... he didn't understand the design patterns and the whole IoC/DI thing. Instead of asking or reading about it, he reverted all the changes while I was 3 weeks on vacation -.-

Such dummy lol.

So.. How did you cope a day deal with it? :p

@lotd
It was pretty odd. The guy was >50 years old and worked there for many years. I was the youngster, 25y/o and worked there for like...a year or so. So I was the "super smart young guy"[sic] who wants to teach the experienced developers how to build an architecture. I mean...I dont want to sound arrogant but this guy got stuck with development a few years a go and wasn't interested in improving anymore. My PM trusted him more than me...this led to some frustrating situations (among with other stuff). I've cancelled the job a few months later :-)

No git. (We used TFS, it was a ASP MVC project ;-)

@thoxx you sir, did the right thing.
