Timeline: 2016 - 2022
Tech Stack
Overview
For 18 years, Ozsale operated as Australia's premier members-only shopping destination, but their success created its own set of challenges. Flash sale events routinely drew 100K+ concurrent users, creating a perfect storm of scalability, inventory management, and user experience problems.
Developmental Challenges
Flash sale traffic spikes are the ultimate stress test—100K users hitting refresh simultaneously while inventory counts down in real-time. The backend needed to handle request queuing and atomic inventory reservation.
Tailored Software Solution
The team chose native iOS (Swift) and Android (Kotlin) for maximum performance. Real-time inventory used a pub/sub system where changes pushed to connected clients via Firebase.
Measurable Results & Impact
Served 2M+ members across Australia and New Zealand, consistently delivering flash sales. The app maintained high ratings and operated successfully until its acquisition in 2025.
