Joined a place where I am the only FE engineer and the product is mature (around 15yrs).

Every single framework you can think of is there. The codebase is such a mess that it makes spaghetti looks neat, organized and logical.

I need to port the code to the latest standard but everything is so bad that tasks that would take a week or 2 max are taking almost a month.

I’m gonna cry. I feel so incompetent even though it’s not my fault.
