What it is
Jet Coffee (Radar Jet Coffee) is a coffee-cart app for Jayapura, Indonesia. Customers find a cart on a live map and order ahead. Sellers run the fleet from one dashboard. Customers get iOS and Android apps; sellers get a Next.js site.
Finding a cart
The map shows where carts actually are, and it updates as they move. That's the whole "radar" idea — find the closest cup and follow it.
Ordering
You pick a cart, customise the drink, and order for pickup. Status updates come back in the app. I wanted it to feel like a normal phone app, not a website stuffed in a wrapper.
Seller dashboard
Sellers can see cart locations, sales, orders, and menus from the web app. It was built so a messy street-cart setup can still be run from a laptop.
Stack
React Native for the apps, Next.js for the dashboard. It's on the App Store and Google Play.
