Hello!
I work a lot with Django, and aware of lots of under-the hood Django stuff. Right now I am responsible for API tests coverage for Django, as there is on-going API refactoring: manually written API methods are replaced with RESTful. Also, testing models was changed from London to Chicago, so I improved my mocking/stubbing best practices a lot.
So, I think, I can also help to provide good quality analytics and code coverage for your API.
Once we can chat, I would like to know more what framework do you use for API, and also how tests are designed. Thank you!
Have a nice day!
