Radio Haanji

Delivered for Australia • Complete engineering overview, architectural decisions, and operational impact.

Executive Summary

Project Overview & Background

Radio Haanji is a premier 24/7 Punjabi digital radio broadcasting network serving listeners throughout Australia (Melbourne, Sydney, Brisbane, Perth) and an expansive international diaspora. The network required a resilient online presence consisting of a high-traffic web platform and high-fidelity mobile applications.

Operational Challenge

The client faced severe audio buffering, intermittent stream dropouts on mobile data connections, and high operating costs from legacy player licenses. Furthermore, listener engagement tools such as show schedule reminders, live studio messaging, and advertiser banners were fragmented.

Stem Technocrats Engineering Solution

Stem Technocrats engineered a dedicated responsive website and single-codebase Flutter cross-platform mobile apps for iOS and Android. The architecture utilizes low-latency Icecast audio chunking, adaptive stream bitrate compression, background audio services, and Firebase Cloud Messaging for scheduled show reminders.
