At Encora Technology, I lead the 1800Flowers iPhone app team and migrated the app from Objective-C to Swift, maintaining it with MVVM, RxSwift, and Clean Architecture. I delivered faster gift search and sending flows, along with gift tracking and contact features.

Earlier, I managed mobile app delivery at Sooryen Technology and developed iOS applications at A3logics India Private Ltd and Dotsquares India Pvt Ltd. Across my work, I’ve delivered 20+ iOS apps, with 30–40% performance improvements, and earned Team Excellence Awards at Encora Inc in 2024 and 2025.
