I’m Indumathi Parvathapuram, a Senior Mobile Application Developer with over 11 years of experience building native Android and iOS apps and cross‑platform solutions. I specialize in Java/Kotlin for Android, Swift/SwiftUI for iOS, and React Native and Flutter for cross‑platform development. I love translating complex requirements into robust, high‑performance mobile experiences and collaborating with product, design, and QA teams to deliver value.
My hands‑on expertise spans Android core components, MVVM/MVP/MVC architectures, REST/GraphQL APIs, push notifications, and performance optimization. I’ve delivered scalable apps for major clients, implemented features like offline data storage, barcode scanning, and integrated with cloud services (Firebase, AWS, Oracle). I’m comfortable leading features from concept to production and continuously improving code quality and maintainability.
