EasyISP

EasyISP is a complete, scalable, cross-platform mobile application for Internet Service Providers. It replaces web-only CRM workflows with dedicated portals for Administrators, Hotspot Users, and PPPoE Users — covering billing automation, real-time analytics, authentication, and payment gateways including bKash.

ISP operations were stuck in web CRM flows. Admins, hotspot users, and PPPoE users needed a single mobile app for login, billing, and day-to-day account actions — including local payment via bKash.

Built a Flutter app with GetX, HTTP/Dio APIs, secure local storage, and separate entry points for Hotspot, PPPoE, and Admin login, plus bKash for payments.

Flutter client (GetX) calls ISP backend APIs over HTTP/Dio. Shared Preferences and Secure Storage keep session tokens and prefs. Role-based portals route admin, hotspot, and PPPoE users into the right flows; bKash handles payment checkout against the billing APIs.

Developed the Flutter ISP client — multi-role login, API integration, secure storage, and bKash payment wiring for production ISP use.
