At Mahindra Software Development Vehicle Center, I extended the Mahindra iOS application’s notification framework to support additional driver safety and business alerts for admin and manager monitoring.

At Hughes Systique Corporation, I developed a React Native group-ordering feature and implemented recent-user caching. I also built OAuth2 SSO with biometric login across iOS and Android, enabling account unification for 5K+ users.

I redesigned a file-download pipeline with intelligent retries and real-time progress tracking, reducing failures by 60%. Earlier, I architected a Firebase-backed file synchronization system that reduced staging conflicts by 50% and migrated 15+ UIKit screens to SwiftUI.

I built ReadingCompanion, a SwiftUI reading companion with private, on-device book recommendations using Apple’s FoundationModels. Its architecture combines MVVM, SwiftData persistence, async/await networking, and an actor-based image cache.
