I've built secure Android platforms for real-time voting and educational-institution comparison, using Kotlin, Jetpack Compose, Firebase, and Clean Architecture.

At Fortran House Technologies, I developed inventory and field-operations tools that improved operational efficiency by 30%. I led a migration of eight Java feature modules to Kotlin, introduced MVVM, and reduced post-release defects by 45% through stronger testing practices.

I've delivered offline-first apps with Room and Retrofit, barcode and QR scanning with ML Kit, location services with Google Maps API, and real-time notifications through Firebase Cloud Messaging. My performance work reduced memory consumption by 25% and improved startup time by 35%.

Earlier at SNET TRACK SERVICES, I built news, e-commerce, and contact-management features in Java and Kotlin, collaborated on API contracts, and helped improve app stability. I bring a practical focus on secure data handling, maintainable code, accessible interfaces, and reliable mobile experiences.
