The challenge
Following prediction markets means watching markets, wallets, and large trades across multiple tabs, and missing a move because you were not looking at the right moment.
What we built
PolyLens pulls live prediction markets, wallet activity, and trade signals into one mobile app backed by a dedicated Django service. It surfaces featured markets and notable movements, follows wallets, compares traders side by side, and fires real-time alerts for large trades, position changes, price moves, and unusual activity. A later version added portfolio tracking with positions and profit and loss.
- Cross-platform Expo app
- Django real-time backend
- Alerting and push pipeline
- App Store release
Outcome
PolyLens is the most involved of these products: a focused mobile front end over a real-time backend that ingests market and wallet data, evaluates alert conditions, and pushes notifications. It is the clearest example of a mobile app and a non-trivial backend shipped together.
