About

I am a highly skilled mobile application developer with extensive experience across iOS and Android platforms. I specialize in delivering robust apps using Swift, SwiftUI, Objective-C, Java, Kotlin, and modern architectures. I thrive in Agile environments, debugging, feature implementation, and managing end-to-end releases to the App Store and Play Store.

I bring strong software design principles, including SOLID, modular architectures, and emphasis on testability. I have hands-on experience with REST and GraphQL APIs, real-time data streams, and CI/CD pipelines using Azure DevOps and other tools. I am committed to collaborating with cross-functional teams to deliver high-quality, scalable mobile solutions.
