Mobile apps in Flutter, with the back end behind them

An app is never just the app

Behind every app there is a server, an admin panel, payments, notifications and somebody who has to run it all. I build the whole thing, so nothing is left for “another developer later”.

• Obadan is two Flutter apps and a back end. Customers build a box of village products and get it on a schedule, paid from a wallet. Couriers get a numbered route, a pickup checklist and a live map. The admin sees every courier moving.
• Zəif Bənd is a real time quiz game on Android for five to nine players at one table, with the server as the only judge of questions, time and money.
• Autoreply is an Android app with its engine in Kotlin, built to keep working when the phone is locked and Android wants to kill it.

Security that holds up

When an app holds money, I treat it that way. In Obadan every session is tied to the device with a key kept in Android Keystore, every request is signed, replayed requests are rejected, and the app trusts only the server’s own certificates.

What you get

The app, the API, the admin panel, the deployment, and app versions with forced updates, so old versions can be retired when needed.
