Production Flutter app with PHP/MySQL backend

Maintained a client's production Flutter app with a PHP/MySQL backend and admin panel, covering debugging, security hardening, token-based authentication and in-app purchase billing.

The problem

The client had a live app and backend that needed ongoing fixes, stronger security and a working billing flow without disrupting existing users.

What I built

Took over the live system, diagnosed and fixed bugs across the Flutter app, PHP/MySQL backend and admin panel, hardened security, implemented token-based authentication and added in-app purchase billing.
