Collard - Comprehensive FinTech & Ticketing Solution

I led the end-to-end development of Collard, a secure FinTech and ticketing app. I architected a highly scalable system using Clean Architecture and BLoC. Key features include integrating Paymob & Amazon Payment Services for secure transactions, and implementing Hive for a flawless offline-first experience in low-network areas. I also built custom Kotlin/Swift bridges for native background tasks. The result is a high-performance app successfully launched on Google Play & the App Store.

I developed and built the Collard application from scratch, a specialized event ticket booking platform currently available on both Google Play and the App Store. The app was designed with a robust software architecture to ensure high stability and performance under heavy user traffic, while delivering a seamless user experience from event discovery to payment completion.
