At Pircle, I designed modular Android architecture and API contracts for production POS and kiosk applications, integrating backend services and payment hardware. I also implemented offline-first persistence and synchronization with Room, WorkManager, and Kotlin Coroutines.
On Resolve Parking, I led Android development for POS, kiosk, ticketing, and multi-POS payment workflows. I designed an architecture that reduced integration effort by 40% and implemented offline-first synchronization that improved reliability by 60% during network outages.
