So, a few years ago I did an internship at this company really close to my house. It was a total disaster but a few months ago I decided to give it another shot and apply for a junior position there as I needed money and they knew me there. For some reason they hired me and now I work there for about 2 months.

There's one other developer here and my problem is that he's the senior here. Guys I don't know what to do about it, this guy is so controlling. He won't allow me to decide ANYTHING.

I have a whiteboard with all my projects and he wrote deadlines there (because his boss said he needs to set deadlines since he never finishes anything on time, but he decided to put that on me) when I finished something in time (like 3 days early!) I wanted to put that under the project on the board. But he didn't want it. No reason. Just no.

He's also constantly talking, all day long. He writes 1 or 2 functions per day. Maybe fixes a small bug. And then one day per week he actually works. Constantly complaining about me, bugging me, removing electricity from my screens, setting my wallpaper to 2 dudes kissing ect. ect. its fucking annoying me. This guy even plays video games on his nintendo or call of duty.. Working for other customers that have nothing to do with this company. And the boss thinks he's great..

So 2 days ago, the whiteboard filled with his drawings was completely emptied because of me. It felt so good, he was so angry he didn't talk all day, to no one. What else can I do guys? I can't go to my boss, the other guy in this office doesn't really care and he's on his side. But when I code I need to be able to concentrate. I can't even have a serious conversation with this guy because he just doesn't take me serious. He always thinks he's right and wants control of every little thing...

What do I do?
