🧑‍💻 Role: Fullstack Developer (solo) ⏱ Duration: 2 weeks (2 weeks dev + 1 week beta-test) 📱 Stack: FlutterFlow · Firebase Auth · Firestore · Storage · Cloud Functions (on-call) · Git versioning

I developed a mobile tennis prediction app for an Italian client, built entirely with FlutterFlow and Firebase. Users can join or create leagues, and make predictions on real-world tennis matches — including winners, scores, and more.

The app features a custom point system that rewards the most accurate predictions. Rankings are updated in real-time via cloud functions, ensuring optimal performance even at scale.

🏆 Main features:

Multiple bet types: predict match winners, exact scores, etc.

Real-time rankings based on match accuracy, with different leaderboards:

Admin dashboard to manage matches, bonus rounds, tennis player data & trigger score calculations

🛠 On the backend, I implemented cloud algorithms to calculate prediction scores and update ranks instantly. Admins can launch score calculations manually from the interface, making the platform both dynamic and flexible.

📈 Impact:

+2,000 users after launch

Smooth and fast UX thanks to API-triggered cloud functions

🌍 The app is fully localized in Italian and optimized for mobile.
