Commerce & delivery
4U — For You
A multi-merchant shopping and delivery app with a merchant console and a super-admin panel: delivery zones, realtime orders, and a subscription-plus-commission billing engine.
My part
The Flutter app, the Laravel backend, and both panels. I designed the billing and subscription engine, the map-based delivery zones, and the merchant's realtime order alert. Money is stored in integer halalas — no floating point anywhere near it.
