How to hire Top Xamarin Developers
Overview
Hiring a Xamarin Developer requires careful consideration of multiple factors, including technical skills, industry experience, and suitability for the company's work environment. Whether you're a startup or a larger company, the role of a Xamarin developer can be integral to your business, as they are responsible for building cross-platform mobile applications using Xamarin, C#, and .NET Framework.
At a startup, a Xamarin developer might need to take on a wider range of responsibilities due to the typically smaller team size. They might be involved in the entire app development cycle, from gathering requirements and design to implementation, testing, and deployment. They might also need to be more agile, adapt to rapid changes, and be able to work in a fast-paced, high-pressure environment. On the other hand, in a larger company, the Xamarin developer's role could be more specialized, working within a larger team and focusing on a specific aspect of the application. They might have more resources and standardized processes, but also more layers of decision-making and bureaucracy.
In terms of employment type, Xamarin developers can be hired on a full-time or hourly basis. Full-time developers are typically more involved in the company, contributing to long-term projects, participating in team meetings, and generally having a stronger understanding of the company's vision and culture. They're often expected to manage their tasks within regular working hours and may be given benefits like health insurance, paid leave, and retirement plans.
Conversely, hiring a Xamarin developer on an hourly basis offers more flexibility, which can be ideal for short-term projects or when you need additional resources during peak periods. Hourly developers can be cost-effective if you have clear, well-defined tasks, but they may lack the depth of understanding of your business that a full-time employee would develop. Additionally, managing and coordinating with hourly developers, especially if they're remote or in different time zones, may require extra effort.
Regardless of the size of your company or the employment type, hiring a Xamarin developer involves evaluating their technical expertise, problem-solving skills, and understanding of mobile app development. Knowledge of Xamarin and its related tools, C# and .NET Framework, proficiency in working with APIs, and familiarity with MVVM design pattern are some key technical skills to look for. Alongside these, the ability to work well in a team, communicate effectively, and fit into the company's culture are equally essential.
Knowledge and Experience with Xamarin
Xamarin is a versatile cross-platform tool used for building applications for iOS, Android, and Windows using C#. Xamarin allows developers to share code, which reduces redundancy and boosts productivity. Thus, it's crucial for a potential Xamarin developer to have robust knowledge and experience in Xamarin.Forms, Xamarin.Android, and Xamarin.iOS. Knowledge of XAML for designing user interfaces and experience with Xamarin's unique features, such as Custom Renderers and Dependency Services, is also crucial. They should have a firm grasp of handling platform-specific functions and customizations, such as invoking native API calls. Furthermore, they should be able to effectively use Xamarin's tools to diagnose and debug runtime issues.
Understanding of C# and .NET Framework
Xamarin uses C# as the coding language and leverages the .NET Framework for cross-platform application development. A proficient Xamarin developer should have a deep understanding of C#, including features like generics, lambda expressions, events, delegates, and asynchronous programming with async/await. They should also be comfortable with .NET libraries and technologies such as Entity Framework, .NET Core, and LINQ. Additionally, they should have a good grasp of Object-Oriented Programming (OOP) concepts, and be proficient in exception handling and debugging in the .NET environment.
Experience with Mobile App Development
Xamarin developers create mobile applications, and thus they need to have a solid understanding of mobile development concepts. This includes knowledge of mobile design principles and standards, experience with touch interface design, and understanding of mobile database management. Proficiency in multi-threading and memory management is also essential to optimize app performance. They should have the skills to handle mobile-specific issues like varying screen sizes, rotation, user interface adaptations, and network issues. Also, an understanding of mobile app lifecycle and experience with app store deployments is crucial.
Knowledge of MVVM Design Pattern
The Model-View-ViewModel (MVVM) design pattern is often used with Xamarin.Forms and is important for building scalable, maintainable, and testable applications. The developer should understand how to separate concerns using this pattern. They should have experience in creating models (that represent data), views (that display the UI), and view models (that bridge models and views). Knowledge of popular MVVM libraries, such as Prism or MVVMCross, would also be beneficial. Additionally, they should understand how data binding works in MVVM, and how it helps to create a clean and organized codebase, which in turn simplifies app maintenance and expansion.
Proficiency in RESTful APIs and Web Services
Mobile applications frequently require data exchanges with server-side applications, often through RESTful APIs. Thus, a Xamarin developer should be proficient in consuming REST APIs, parsing JSON or XML data, and handling network responses, including errors. They should be familiar with HttpClient for making network requests and understand async programming for handling these requests. Knowledge of OAuth and other authorization methods is also critical for secure data exchanges. Additionally, experience with SOAP-based web services can be beneficial, as some legacy systems still use this protocol.
Familiarity with Xamarin Libraries and Tools
Beyond the core Xamarin frameworks, there are numerous libraries and tools that can enhance the productivity of a Xamarin developer. Knowledge of Xamarin.Essentials, which provides access to common native device features, is a big plus. Proficiency with the NuGet package manager to install and manage these libraries is essential. Familiarity with XAML for designing user interfaces is also important. For tooling, the developer should be adept at using Visual Studio, the primary IDE for Xamarin development, including its debugging and profiling tools.
Problem-Solving Skills and Creativity
Developing mobile applications with Xamarin, like any software development, often involves tackling challenging and unexpected problems. A good Xamarin developer should have strong analytical skills and be able to solve complex programming issues. They should be proficient in debugging techniques and using tools provided within the Xamarin and .NET ecosystem to diagnose issues. Creativity also comes into play when devising solutions that meet both functional and performance requirements. Furthermore, they should be capable of thinking ahead to foresee potential issues and mitigate them proactively.
Soft Skills and Cultural Fit
Technical skills alone don't make a great Xamarin developer. They must also possess solid communication skills to effectively collaborate with team members and stakeholders. They should be capable of explaining complex technical issues in layman's terms to non-technical colleagues or clients. Strong time management and organization skills are essential for managing tasks and meeting deadlines. Being receptive to feedback and having a continuous learning mindset are also valuable traits. Finally, it's important to consider if a candidate's attitude and work style align with your company culture to ensure a harmonious working relationship.

Frequently Asked Questions
Are Xamarin developers in demand?
Xamarin developers continue to be in demand. With the increasing need for businesses to have mobile applications that work across multiple platforms, Xamarin's ability to create cross-platform apps with a shared C# codebase makes it a popular choice. Developers skilled in Xamarin can help businesses reach a larger audience without the added cost and time of developing separate applications for Android, iOS, and Windows. Additionally, Xamarin's integration with Microsoft's .NET platform adds to its appeal for businesses already working in a .NET environment.
Is Xamarin outdated?
Xamarin is not outdated. It's a modern framework actively maintained by Microsoft and used by many organizations for cross-platform mobile application development. Xamarin leverages the power of .NET and C#, which are widely used and actively developed technologies. Furthermore, Xamarin supports the latest versions of Android and iOS, allowing developers to use the latest features from these platforms. Xamarin is being evolved into .NET MAUI (Multi-platform App UI), a unified framework replacing Xamarin.Forms.
What is the hourly rate of a Xamarin developer?
The hourly rate of a Xamarin developer varies based on factors like geographic location, experience level, and the complexity of the project. In the United States, you might expect to pay anywhere from $50 to $150 per hour for a Xamarin developer. Developers in other regions, such as Eastern Europe or India, might charge less due to lower living costs. It's also worth noting that freelance or contract developers might charge more than an equivalent full-time employee due to the absence of benefits like health insurance.
What is the future of Xamarin?
The future of Xamarin lies in .NET MAUI (Multi-platform App UI), which is being developed by Microsoft to consolidate Xamarin.Forms, Xamarin.iOS, and Xamarin.Android into a single framework. This transition is part of Microsoft's larger effort to unify .NET into a single platform that can be used for all types of application development. .NET MAUI aims to provide a more streamlined development experience and better performance than Xamarin.Forms. Microsoft has promised a straightforward migration path to .NET MAUI, indicating a sustained commitment to the Xamarin developer community.
Which database is best for Xamarin app?
The choice of database for a Xamarin app depends on the specific needs of your project. SQLite is a popular choice for local data storage due to its light footprint and the availability of libraries that make it easy to interact with in C#. It supports most SQL syntax and can handle complex queries. For applications with real-time data requirements, Firebase can be a good choice due to its real-time database and plethora of other useful services. If you need offline sync capability, Azure Mobile App Services provide this functionality along with a scalable backend. If you have complex data needs, you might also consider NoSQL databases like MongoDB or Couchbase.
What does Xamarin mostly use?
Xamarin primarily uses C# and .NET framework for creating mobile applications. It leverages the .NET environment to provide a single language (C#), class library, and runtime that works across multiple platforms. Developers write UI code in XAML and can share code across Android, iOS, and Windows. Xamarin also integrates with Visual Studio, Microsoft's IDE, providing a familiar and robust development environment for developers. Xamarin.Essentials is another tool often used in Xamarin development to access native features like geolocation, connectivity, sensors, and app settings.
Is Microsoft Xamarin discontinued?
Microsoft announced the evolution of Xamarin into .NET MAUI (Multi-platform App UI), a more unified framework for building cross-platform applications. The transition isn't about discontinuing Xamarin but rather evolving it into a more streamlined platform. Microsoft has provided support for Xamarin products until November 2022 and then adopted a clear migration path to .NET MAUI, allowing developers to transition their existing Xamarin projects to the new framework.
Who bought Xamarin?
Xamarin was acquired by Microsoft in 2016. This acquisition helped integrate Xamarin's cross-platform development tools more deeply into Microsoft's ecosystem, leading to Xamarin becoming a key part of Microsoft's mobile app development offering. Microsoft's acquisition of Xamarin also reflected the company's broader strategy of embracing cross-platform technologies and open-source development. Since the acquisition, Microsoft has continued to maintain and develop Xamarin, and as mentioned before, is evolving it into .NET MAUI.
