we're finally over the hump with the project
A 'hump', in this context, is the same as a 'bump'. It can describe the most difficult, boring or dangerous part of a job or activity. Colloquially, Wednesday is referred to as 'hump day', because once it has passed, you are closer to the weekend. When you 'get over the hump', you surpass the most challenging part of something. This is a casual, colloquial expression.
