Is NOBODY wrong in the post ? POST : Hullo reddit

Right now I am working as a web developer wherein I am working on a project on this framework which I hate(it's a php based framework and it ends in "ento "). The project has been worked on by 2 parties and they had asked the other party to do only half the work and the other half I have to understand their code and finish it. I have finished my end of the functionality but it's ridiculous that I have to finish their job. And I've had to literally modify almost all major modules in some way or the other. 

I am really really  starting to hate my job which was not the case earlier. 

The reason why I took this job because I was asked to leave from my earlier data science job as I did not have enough knowledge about the same. 

So AITA if I hate my job?
