At Creative Chaos, I architect Android modules for Putco’s South African transit payment system, supporting secure ticketing across bus-terminal hardware. I built offline-first transaction timestamping, wallet SDK telemetry, and a real-time ZeroMQ layer that reduced latency by 30% and improved low-connectivity reliability by 40%.
Across consulting, eZhire, and Appsware Technologies, I’ve shipped Kotlin Android applications from architecture through Play Store release, supported 50,000+ active users, and reduced crashes by 35% through Java-to-Kotlin and Jetpack modernization. I also contributed to Intelligent CV Builder at 10M+ Google Play downloads and build shared Android/iOS applications with Kotlin Multiplatform.
