I'm an Android Developer with 4+ years of experience architecting offline-first, MVVM-based applications in Kotlin and Jetpack Compose for enterprise retail (POS) systems. Currently at Ginni Systems Limited (Ginesys), I own the Android architecture behind Zwing POS — delivering secure payment integrations, sub-2% defect rates, and measurable efficiency gains for 50+ enterprise clients. I also work with reverse engineering, security analysis, and mobile application debugging to optimize and secure apps effectively.
