You’ve probably used products built by our Xamarin developers.
We've been delivering Xamarin development services for more than a decade. Today, we also help clients modernize legacy Xamarin apps and migrate to .NET MAUI for improved performance and longevity.
We build full Xamarin apps from discovery through launch. Our architects define a shared C# core, establish type-safe data models, and set up CI pipelines early. In the first sprints, our engineers implement navigation, authentication, and data flow, the foundations every feature depends on. You receive a cross-platform product that meets performance targets, integrates cleanly with existing services, and ships reliably.
Microsoft ended Xamarin support in 2024, but you don't have to freeze feature delivery. We migrate your Xamarin app to .NET MAUI through a phased approach—running parity audits, wrapping legacy screens in feature flags, and upgrading storage, auth, and third-party plugins incrementally. Users never see downtime, and your team continues shipping features during the migration.
Not every organization can migrate to .NET MAUI immediately. We provide ongoing maintenance for existing Xamarin applications. Our engineers fix critical bugs, apply security patches, and ensure compatibility with new iOS and Android releases. Our work keeps your app stable and functional while you plan your migration timeline.
Poor test coverage leads to app store rejections, negative reviews, and emergency hotfixes. We provide dedicated QA engineers who integrate directly into your development workflow. Our teams build automated test suites, execute device testing across BrowserStack or AWS Device Farm, and validate critical user flows before each release. You get production-ready apps that pass store review on first submission and maintain quality as features evolve.
Enterprise Xamarin apps must connect to multiple backend systems, such as ERP, CRM, legacy databases, and third-party APIs. We design and implement integration layers that handle authentication, data transformation, and error handling across these systems. Our engineers build resilient middleware that manages connectivity issues, implements retry logic, and maintains data consistency. You get reliable integrations that keep mobile users productive even when backend systems are unstable.
When your app needs platform-specific polish, camera access, motion sensors, or in-app purchases, we implement fully native modules and keep them contract-tested in the same repo as the shared code. Each component ships with its own CI validation, change log, and sample usage. So you get native performance without fragmenting the codebase.
Organizations with multiple Xamarin apps need consistent UI components across products. We build reusable component libraries in Xamarin.Forms or .NET MAUI, package them as versioned NuGet modules, and document them in Storybook. Our engineers implement design tokens for color, spacing, and typography, add accessibility controls, and validate components through CI. So your teams can pull consistent UI elements from a single source, eliminating duplicate development work.
