I really need to vent. Devrant to the rescue! This is about being undervalued and mind-numbingly stupid tasks.

The story starts about a year ago. We inherited a project from another company. For some months it was "my" project. As our company was small, most projects had a "team" of one person. And while I missed having teammates - I love bouncing ideas around and doing and receiving code reviews! - all was good. Good project, good work, good customer. I'm not a junior anymore, I was managing just fine.
After those months the company hired a new senior software engineer, I guess in his forties. Nice and knowledgeable guy. Boss put him on "my" project and declared him the lead dev. Because seniority and because I was moved to a different project soon afterwards. Stupid office politics, I was actually a bad fit there, but details don't matter. What matters is I finally returned after about 3/4 of a year.

Only to find senior guy calling all the shots. Sure, I was gone, but still... Call with the customer? He does it. Discussion with our boss? Only him. Architecture, design, requirements engineering, any sort of intellectually challenging tasks? He doesn't even ask if we might share the work. We discuss *nothing* and while he agreed to code reviews, we're doing zero. I'm completely out of the loop and he doesn't even seem to consider getting me in.

But what really upsets me are the tasks he prepared for me. As he first described them they sounded somewhat interesting from a technical perspective. However, I found he had described them in such detail that a beginner student would be bored.
A description of the desired behaviour, so far so good. But also how to implement it, down to which classes to create. He even added a list of existing classes to get inspiration or copy code from. Basically no thinking required, only typing.

Well not quite, I did find something I needed to ask. Predictably he was busy. I was able to answer my question myself. He was, as it turns out, designing and implementing something actually interesting. Which he never had talked about with me. Out of the loop. Fuck.

Man, I'm fuming. I realize he's probably just ignorant. But I feel treated like his typing slave. Like he's not interested in my brain, only in my hands. I am *so* fucking close to assigning him the tasks back, and telling him since I wasn't involved in the thinking part, he can have his shitty typing part for himself, too. Fuck, what am I gonna do? I'd prefer some "malicious compliance" move but not coming up with ideas right now.
