Firebase Developer for Mobile App

Project Brief: Player Analytics + Manager Dashboard for HTML5 Learning Games What I need I have two (soon three) browser-based English-learning games, built in HTML/JavaScript, currently distributed via GitHub Pages / wrapped for Google Play. I need player tracking added, plus a simple web dashboard so training managers can see how their staff/students are progressing. Current setup Games are plain HTML/CSS/JavaScript — no existing backend, no user accounts, no login system Hosted via GitHub Pages Two games now (a third in development), all should feed into the same tracking system Scope of work 1. Firebase backend Set up one Firebase project (Realtime Database or Firestore — your call) Store per player: name/ID, which game, score, date/time played, number of plays Basic security rules so data can't be tampered with from the browser 2. Game code integration Add Firebase SDK to the existing HTML/JS game files At the end of each game session, send score + player info to Firebase automatically No changes to gameplay, visuals, or existing text — tracking only Handle the case where a player has no internet connection when they finish (queue and sync later) 3. Manager dashboard (web page) Simple login (email + password) for training managers Manager sees a list of their players, with: Score(s) per game Number of times played Last played date Whether scores are improving over time Button to export the data as a CSV Must work on both desktop and mobile browsers 4. Deliverables Firebase project set up and handed over to me (I own the account/credentials) Updated game files, ready for me to publish myself Working dashboard, hosted (Firebase Hosting or similar free/cheap tier) Short written instructions: how a manager signs up and adds players One short call (30 min) to walk me through it Timeline 2–3 weeks Questions for you to answer in your quote Have you integrated Firebase into HTML/JavaScript projects before? (please link an example if possible) Your fixed price for the full scope above Your estimated delivery time Whether ongoing Firebase hosting/maintenance costs are separate from your fee (they should be — I'll pay Google directly)
