Urgent Express.js Web App Support

I’m racing to finish a Node-based web application and need an Express.js specialist to jump in immediately. The core project is already under way: routes, middleware structure, and an initial MongoDB layer exist, but several key features still need to be written, optimised, and tested.

Here’s what I need from you right now:
• Complete or refactor existing Express routes so they follow best practices and stay fully RESTful.
• Wire remaining data operations to MongoDB (CouchDB experience is a plus).
• Fix any blocking bugs, add concise unit tests, and make sure everything runs without warnings in the current Node environment.
• Push clean, well-documented code to our Git repo so I can review quickly and deploy.

Time is critical—I’m looking to merge your first commit within the next 24-48 hours and wrap the remaining tasks as soon as humanly possible. If you live and breathe Express, can debug fast, and write clear code, let’s get started right away.
