Billing System RT/RW Net

About

RT/RW Net Billing System is an internal management platform built for a local ISP (Internet Service Provider) using Golang with an SSR monolith architecture. The system streamlines subscriber management, invoice generation, and payment tracking — and integrates with Mikrotik for network-level user management. Built during my internship at Amang-Wifi.
