Efficient feature deployment in cross-platform applications

We supported a client from Iceland in delivering advanced cross-platform mobile applications built with Xamarin. The main goal was to create fully functional apps for Android, iOS, and Windows Phone integrated with SharePoint systems, while rapidly scaling the client’s development capacity and maintaining high-quality solutions for end users. This approach enabled faster feature delivery, improved app stability, and seamless user experiences across multiple platforms.

Challenge

Rapid scaling of xamarin expertise while maintaining stability

The client faced the challenge of quickly building a Xamarin team capable of handling multiple mobile projects simultaneously, while maintaining application stability and performance. Technical challenges included:

  • Supporting Android, iOS, and Windows Phone simultaneously
  • Integrating app functionalities with SharePoint systems
  • Ensuring high quality and reliability under an accelerated deployment schedule

The client needed to rapidly scale Xamarin expertise – without engaging in the internal recruitment and onboarding process.

Solution

Xamarin project team - from architecture to integration

We provided a complete project team including developers, testers, and UX/UI designers who were responsible for designing, implementing, and testing Xamarin-based mobile applications. The team built app architectures, implemented features using Xamarin.Forms and native components, and ensured seamless integration with SharePoint systems. By taking over technical execution, we allowed the client to focus on strategic priorities while guaranteeing app quality and stability.

Key responsibilities

We handled app architecture design, feature implementation, functional and integration testing, and integration with SharePoint systems. This enabled end-to-end delivery of high-quality mobile solutions.

Project highlights

Three major applications were delivered:

  • Internal Social App for Employees: Facilitated sharing company updates, events, lunch menus, and contacts via SharePoint.
  • Emergency Services App: Allowed users to send real-time information about their condition and location and contact emergency services instantly.
  • Business Management App: Displayed key business information including contacts, clients, projects, tasks, emails, documents, and meetings, all synchronized with SharePoint.
Results

Three functional apps and measurable business outcomes

The partnership with us allowed the client to access a dedicated 14-person development team without internal hiring. Development timelines were reduced by 40%, and three fully functional cross-platform apps were launched with seamless SharePoint integration. Each solution could be easily adapted to end-user requirements, enhancing user satisfaction, streamlining operational processes, and improving overall business efficiency.

FAQ

FAQ - Xamarin and .NET MAUI Mobile Applications

What are Xamarin and .NET MAUI, and why use them?

Xamarin is a cross-platform framework for building native Android, iOS, and Windows apps using a single C# codebase. .NET MAUI (Multi-platform App UI) is its modern successor, offering improved performance, desktop support, and more flexible UI design. Both frameworks allow faster app development while maintaining consistent user experience and high quality.

What are the business benefits of cross-platform app development?

30–40% faster feature rollout compared to native development.

Reduced development and maintenance costs.

Consistent UX/UI across mobile (Android/iOS) and desktop (MAUI).

Seamless integration with enterprise systems like SharePoint, ERP, and CRM.

How to ensure app performance and stability in Xamarin/.NET MAUI?

Modular and scalable code architecture.

Automated and manual functional and integration testing.

Continuous monitoring in production environments (CI/CD).

Optimization of native components and device resources.

Are Xamarin and .NET MAUI suitable for enterprise solutions?

Yes. Both frameworks support scalable, secure mobile apps with enterprise system integration, enabling document management, workflow, and real-time collaboration. .NET MAUI also extends support to desktop platforms, aligning with modern enterprise requirements.

What are the current trends in cross-platform mobile development?

Migration from Xamarin to .NET MAUI for higher performance and multi-platform support.

Increased use of native device features (AR, GPS, push notifications, biometrics).

Real-time integration with cloud and enterprise systems.

Agile development and CI/CD pipelines for faster delivery to end users.
