Tech Stack
Swift
For iOS applications, we use Swift – a modern, secure, and high-performance language from Apple. It allows us to develop customized and stable apps that integrate seamlessly into the Apple ecosystem.
Flutter
At Diamir, we rely on Flutter to develop high-performing and visually appealing cross-platform apps with a shared codebase for iOS and Android. This saves time, reduces costs, and delivers consistent user experiences across all devices.
Ionic
With Ionic, we develop modern hybrid apps for iOS and Android based on web technologies such as HTML, CSS, and JavaScript. The framework enables rapid development, native functionality, and a consistent user experience across all devices.
Kotlin
Kotlin is our preferred language for Android apps. It’s expressive, reliable, and fully compatible with Java. With it, we build robust Android applications that meet modern standards and are future-proof.
React Native
With React Native, we develop mobile apps that look and perform natively. Thanks to the reusability of components, we can respond flexibly to requirements and create fast, scalable solutions for different platforms.
Kotlin Multiplatform
With Kotlin Multiplatform, we develop cross-platform apps where logic for iOS, Android, and web can be efficiently shared. This reduces development effort, avoids redundant code, and delivers native performance on all target systems.
