React Native

React Native is a popular open-source framework created by Facebook, enabling the creation of native mobile applications for iOS and Android platforms using JavaScript and React. Thanks to the “write once, run anywhere” approach, it allows for significant time and resource savings during mobile app construction.

1. Shared code for iOS and Android – Ability to create apps for both platforms with a single codebase, accelerating development and facilitating maintenance.
2. Near-native performance – React Native uses native UI components, ensuring smoothness and high application performance.
3. Broad community and support – A large number of ready-made libraries, active community, and support from Facebook and other companies.
4. Hot Reloading – A feature allowing immediate viewing of code changes without restarting the application.
5. Easy integration with native code – Ability to extend the application with native modules in Objective-C, Swift, or Java/Kotlin.
6. Openness and development – The framework is constantly developed, with new features and fixes appearing regularly.

1. Limitations in access to native APIs – Some advanced functions require writing native modules or using additional libraries.
2. Compatibility issues – Updates to the framework or libraries can cause conflicts and require additional work.
3. Performance in very complex apps – In the case of very extensive applications, native solutions may be more efficient.
4. Reliance on community – Some libraries may be poorly maintained or outdated.

React Native integrates with many tools and services, such as Redux, TypeScript, GraphQL, Firebase, Expo, as well as native modules and libraries. Thanks to support for popular CI/CD tools and testing platforms (e.g., App Center, Bitrise), deployment and testing automation is possible. The React Native ecosystem is constantly developing, offering more and more solutions for developers.

• Flutter: Flutter (Google) offers very high performance and its own UI rendering engine, but React Native is closer to native components and has a larger community.
• Swift/Kotlin (Native): Native solutions ensure maximum performance and access to all platform functions but require separate teams and code for each platform.
• Xamarin: Xamarin (Microsoft) allows code sharing in C#, but React Native is more popular and has a richer ecosystem.

•  Maintenance and development of IT systems (web applications, websites)
• Design and development work (creating new functionalities, expanding existing systems)
• User support and software engineering consulting
• Software quality assurance (testing, audits, optimization)
• IT project management (project leadership, consultations, workshops)
• DevOps services (server monitoring, updates, security, infrastructure maintenance)
• Design and implementation of dedicated solutions (including system integrations)
• Business and technology consulting (analysis, recommendations, process optimization)
• Post-implementation and service support (hypercare, rapid response to tickets, SLA)
• Graphic design and UX/UI services (for application and website development)
