Overview
A comprehensive billing and bandwidth management SaaS for Internet Service Providers in Bangladesh. Features full MikroTik RouterOS API sync, FreeRADIUS authentication, MFS payment integrations (bKash, Nagad), and a Python FastAPI ML microservice for automated bandwidth optimization.
Outcome Results
The Challenge
ISP operations are highly real-time, requiring zero-delay bandwidth shaping, immediate customer disconnects/reconnects on billing events, and compliance with strict BTRC log-keeping standards, all while scaling to support multiple ISP tenants.
The Solution
Architected a multi-tenant platform communicating with MikroTik routers via optimized API queues. Integrated automated bKash/Nagad checkout APIs, set up FreeRADIUS for central billing authorization, and built a FastAPI microservice predicting usage peaks. Fully structured BTRC-compliant activity logging.
