Hiring Guide: Xamarin Developers

Looking to hire Xamarin developers? Xamarin is a cross-platform framework by Microsoft that allows developers to build native Android, iOS, and Windows applications using a single C# codebase. It combines the power of the .NET ecosystem with native performance and UI capabilities, making it an ideal choice for businesses aiming to launch multi-platform mobile apps efficiently. Hiring experienced Xamarin developers ensures your apps deliver native-like speed, functionality, and user experience without the high costs of maintaining separate codebases.

Why Hire Xamarin Developers?

Xamarin developers bring together cross-platform development efficiency and native-level performance. They specialize in writing shared business logic across platforms while maintaining platform-specific UI components. For startups and enterprises alike, Xamarin significantly reduces time-to-market, simplifies maintenance, and improves code reusability—all while leveraging the robustness of Microsoft’s .NET ecosystem.

Core Responsibilities of Xamarin Developers

Develop, test, and deploy cross-platform mobile applications for iOS, Android, and Windows using Xamarin.Forms or Xamarin.Native.

Integrate apps with backend services and APIs, including RESTful and GraphQL endpoints.

Implement shared codebases using C# and .NET MAUI, ensuring consistency and scalability across platforms.

Build and optimize user interfaces for responsiveness, accessibility, and platform-specific design standards.

Integrate third-party libraries, payment gateways, and cloud storage solutions such as Azure or AWS.

Utilize Xamarin.Essentials for hardware integration including GPS, sensors, and cameras.

Conduct performance profiling and debugging across platforms using Visual Studio and native emulators.

Implement unit, integration, and UI tests to maintain code quality and prevent regressions.

Key Technical Skills to Look For

Languages & Frameworks: C#, .NET, Xamarin.Forms, Xamarin.Native (Xamarin.iOS and Xamarin.Android).

Tools: Visual Studio, Visual Studio for Mac, NuGet, Azure DevOps.

Architecture Patterns: MVVM, Dependency Injection, Reactive Programming.

Mobile SDKs: Android SDK, iOS SDK, and Xamarin.Essentials.

Backend Integration: REST APIs, gRPC, Firebase, or Azure Functions.

Testing & CI/CD: NUnit, xUnit, App Center, Jenkins, or GitHub Actions.

Databases: SQLite, Realm, and Azure Cosmos DB.

Version Control: Git, GitHub, Bitbucket, or Azure Repos.

When to Hire Xamarin Developers

When building cross-platform applications with native-like performance.

When reducing development costs while maintaining a native UI experience.

When you already use Microsoft technologies (.NET, Azure, C#) and want ecosystem continuity.

When migrating legacy .NET applications to mobile platforms.

When you require fast iterations and consistent features across Android and iOS devices.

How to Hire the Right Xamarin Developer

1. Define Your Project Scope and Architecture

Clarify if your project will use Xamarin.Forms (for shared UI and faster development) or Xamarin.Native (for more custom and platform-optimized experiences). This helps target the right talent for your needs.

2. Evaluate Cross-Platform Proficiency

Review prior projects to confirm candidates have experience building production-grade apps using Xamarin.Forms and integrating native SDKs. Ask them to demonstrate performance optimization and platform adaptation skills.

3. Interview Questions

What are the key differences between Xamarin.Forms and Xamarin.Native?

How do you manage shared code and platform-specific implementations in Xamarin?

Explain how Xamarin integrates with native APIs and UI components.

What strategies do you use to optimize app performance across devices?

How do you handle data storage and offline support in Xamarin applications?

4. Technical Assessment

Assign a small test project: create a basic cross-platform app using Xamarin.Forms with local data storage (SQLite) and simple navigation between screens. Evaluate their ability to implement clean architecture and handle both platforms efficiently.

Average Cost of Hiring Xamarin Developers

Xamarin developer rates vary depending on skill level and project complexity:

Junior Developers (1–3 years): £40–£60/hour — capable of building basic cross-platform apps with guidance.

Mid-Level Developers (3–6 years): £70–£100/hour — experienced in full-stack app architecture, UI design, and backend integration.

Senior Developers (7+ years): £110–£150/hour — experts in large-scale applications, performance optimization, and cloud-based integrations.

At Lemon.io, you can hire pre-vetted Xamarin developers who build high-quality, scalable, and cross-platform apps using the latest Microsoft technologies.

Frequently asked questions

You can find Xamarin developers through outsourcing IT vendors or freelance platforms, such as Toptal or Upwork. Although Microsoft retired the technology in May 2024, many experienced software engineers can provide ongoing maintenance and support services or help transfer Xamarin apps to a new infrastructure.

You can also rely on Lemon.io to match you with a vetted full-time or part-time Xamarin developer. We will analyze your project requirements, select the best-suited developer from our talent pool, and set up an interview within 48 hours.

For a no-risk trial period for hiring a Xamarin developer on Lemon.io, you can get a 20-hour paid trial before committing to a weekly or monthly subscription. It will let you evaluate the developer’s skills before they start working on your project. Moreover, if the developer’s output does not match your requirements, we can match you with a more suitable software engineer or issue a refund for up to 40 hours. Use the “Report a problem” feature in your client’s account and specify your reasons for requesting a new developer.

Xamarin developers are not in high demand, considering Microsoft support stopped on May 1, 2024. At the same time, many Xamarin-based applications haven’t been updated yet. As a result, businesses rely on Xamarin developers to help support legacy applications and integrate them with new solutions. Until app owners update all the Xamarin-based products, the demand for Xamarin developers will remain, even if not as high as it used to be in its heyday.

You can hire a Xamarin developer in under a week through Lemon.io. After you fill out the form and share your project’s requirements, we’ll analyze our talent pool and match you with the best-suited developer within 48 hours. We’ll share their CV and set up an interview or a live coding call. If you’re happy with the Lemon.io candidate, you can add funds to your balance, and the developer will start working on your project within a day or two.

Xamarin developer charges around $55 per hour across the US, with an annual wage of around $144,000, according to Glassdoor. At the same time, the hourly rate depends on the developer’s experience, the project’s complexity and timeframe, additional requirements, and the engineer’s location. The highest rate can exceed $80/hour. In contrast, offshore outsourcing vendors may offer the services of low-grade developers for as low as $11 per hour.

The vetting process for developers at Lemon.io includes four stages. First, we screen the candidates based on their stack, experience, and soft skills. Next, we evaluate their CVs and professional profiles. A screening interview with a recruiter helps us check basic coding skills and English proficiency, while the final technical interview includes live coding tasks. This rigorous vetting process facilitates developer selection for our clients, speeds up onboarding, and lets you start working on your project sooner.

Your business can benefit from hiring a Xamarin developer to transfer a cross-platform app to .NET MAUI, Flutter, or React Native. Although Xamarin is currently discontinued, it was actively used for application development at some point, so the demand for professionals familiar with this framework still exists.

And even if you don’t plan on moving a Xamarin-based app to another framework, you’ll still need a knowledgeable developer who can help you support and maintain the existing solution.

You should use Lemon.io to hire developers and benefit from our developer vetting and quick hiring process. We thoroughly check every candidate’s technical and soft skills before they join our talent pool, and we match them to your project requirements. You can schedule an interview with the developer within 48 hours of sharing your project details, and if the interview goes well, your developer can start working almost immediately.
