For DarinX: Online Learning Tool (Video, Chat, Whiteboard, Etc)

We're looking at building an online learning tool similar to [login to view URL] & [login to view URL] --- Every feature you see in this demo we need in our V1. Live code editing and collaboration, live text editing, video chat, whiteboard, etc. Keep in mind >>> The Tool has already been designed. The live video, chat, text collaboration and coding has already been built from 3rd party APIs or from open source libraries. Also, the back-end and server infrastructure has already been built by Firebase & Firestore (just needs setup and integration) So we're looking for an expert engineer who can piece all these functions together and integrate with the back-end and code a few more pieces to bring the app together. --- Required API's and Libraries Node.JS Firebase (Hosting & Tools) [login to view URL] Firestore (Live DB) [login to view URL] Firepad (collaborative code & text editor) [login to view URL] & [login to view URL] TokBox API (WebRTC Live Video/Chat) [login to view URL] -- V1 Features Needed Firebase Backend Setup & API connections with TokBox/Firepad Whiteboard Document Upload Send files Export & save work Graphing Equation Editor Wolfram Alpha API Integration --ALREADY DONE-- Design (Already Done) Collaborative Code editor (firepad) - (Already Done) Collaborative Text editor (firepad) - (Already Done) Video/Audio & Chat & Screenshare (tokbox) - (Already Done)
