    As a mobile app/SDK development contractor/consultant with 10 years of experience, I specialize in native app development for both Android and iOS using Kotlin and Swift. I have a thorough understanding of the mobile app development lifecycle, including UI/UX design and app architecture. I work with a dedicated mobile team to deliver high-quality mobile apps and SDKs that meet your business requirements. I have extensive experience in integrating third-party APIs and libraries, as well as implementing complex features such as push notifications, in-app purchases, and location-based services. On the other hand, I have experience with Kotlin Multiplatform Mobile (KMM), a new technology that allows developers to write shared business logic for mobile apps using Kotlin. With KMM, you can significantly reduce the time and cost of app development, while still delivering high-quality, native mobile apps for both Android and iOS platforms. The benefits of using KMM include faster development cycles, reduced code duplication, and easier maintenance. With KMM, you can write shared code for features like data models, networking, and business logic, while still using native UI components and platform-specific APIs. This approach allows you to deliver a seamless user experience on both platforms, without compromising on performance or quality. In addition to mobile app development, I also provide consulting services, including technical guidance, project management, and ongoing support. My goal is to help you achieve success with your mobile app project, from concept to launch and beyond.
