Hi,
Yes we have experienced developers for MongoDB, ExpressJS, AngularJS and Node.js. As you said that 33% is completed, but it seems if code is not well commented, we might need to do from start.
We can do this project is two ways:
1) Either you outsource the project to our team
2) One of our dedicated team member shall work with your team
Let me know your views.
Regards,
Mit-
