PHP Admin panel for mobile app fetch data update

Existing php admin panel designed to give better visibility management for a SAAS mobile app users. Backend is in node.js so you must be experienced in Node JS. I recently changed the mobile app and store lots of new data, the data is stored in mongo db and node.js is backend and i want to be able to view data easily in admin panel, so you will need to fetch this data and create new UI for new pages. I have a list of items. (mobile app is SAAS). You will need to get familiar with frontend content of mobile app as well.
Looking for someone experienced, works in USA Timezone, and communicates well.
