Cross-platform mobile developer with ~9 years of full-time experience building and shipping iOS and Android apps that have served 100,000+ users across 15+ projects.
I started as a .NET/C# developer and grew into cross-platform mobile — today I build with Flutter and React, and I still take on Xamarin and .NET MAUI maintenance and migration work that many developers won't touch.
What I bring to your project:
Full ownership from architecture to store launch — MVVM, clean architecture, REST/OAuth integration, and CI/CD (App Center, Bitbucket Pipelines).
A track record of results, not just code — e.g. cutting one app's startup time by 50% through profiling and optimization.
Complete lifecycle support: app signing, App Store/Play Store distribution, push notifications, crash monitoring, and localization (fluent Arabic + English).
Whether you need a new cross-platform app built from scratch, an existing one made faster and more stable, or a legacy Xamarin app modernized, I'll deliver clean, maintainable work and clear communication throughout.
Let's talk about what you're building — send me the details and I'll tell you exactly how I'd approach it.

I've spent 11+ years building production .NET systems for companies like Canon, PSA, Sodexo, Bolloré and Ceva — and today I'm the senior backend engineer on a multi-tenant B2B SaaS platform in the energy-efficiency sector: four client portals, one modular .NET 9 codebase, running in production under strict quality gates.
What I do best:
• ASP.NET Core APIs — versioned REST APIs, role-based access control, multi-tenant architecture, FluentValidation, clean vertical-slice structure
• Azure data — deep Cosmos DB expertise (partition design, change-feed pipelines, indexing policies, zero-downtime backfills) plus SQL Server, PostgreSQL and EF Core with disciplined migrations
• Architecture — modular monoliths and microservices done right: CQRS, DDD, MediatR, Result-based error handling, contracts that never break consumers
• Integrations — e-signature providers, rate-limited government APIs, registry exports with strict file formats, RabbitMQ, Redis, SignalR real-time
• Full-stack when the job needs it — Angular, React and TypeScript front-ends shipped in production at Sodexo, Bolloré, TUI and Canon
• Quality — TDD with xUnit, SonarQube-clean code, benchmark-driven performance work. Every change ships production-ready.
How I work: small verified increments, before/after evidence for every performance claim, honest estimates, no surprises. My code survives strict senior review every single day — yours will get the same standard.
Available now for full-time or part-time engagements (100% remote, CET) — I reply daily.
Send me your API, performance, or migration problem and you'll get a concrete first step within 24 hours.

How to Hire Top Xamarin Developers
How to hire Xamarin developers
How do you find the right Xamarin expert to help your business create, develop, or integrate multi-platform software with Mono, Mono-Touch, or Mono for Android? Here’s an overview of what you can do to find, hire, and work with an independent Xamarin professional.
How to write an effective Xamarin developer job post
With a clear picture of your ideal Xamarin professional in mind, it’s time to write your job post. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.
An effective Xamarin job post should include:
Scope of work: From specific functionality to documentation, list all the deliverables you’ll need.
Project length: Your job post should indicate whether this is a smaller or larger project.
Background: If you prefer experience with certain industries or applications, mention this here.
Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.

Native vs. Xamarin
In the world of mobile development, you can either develop native mobile apps specifically for iOS, Android or Windows, or you can opt for two other routes—hybrid apps or cross-platform apps.
While native apps offer incomparable performance and user experience, not every company has the resources to develop native apps for each platform. Cross-platform software in particular has created a flexible, efficient alternative to native apps, yielding apps that can run on multiple platforms and devices without having to be entirely rewritten for each.
But accomplishing a native user experience without native app code comes with a few compromises: larger app file size, differences in performance, more code overhead, and in some cases, the cost of the platform itself. Not all cross-platform softwares are created equal, but some offer advantages that might be better suited to your mobile app goals.
So which route should you take? To help you weigh the pros and cons of native vs. cross-platform before kicking off your mobile project, here’s a comparison of native apps with one of the most popular cross-platform solutions, Xamarin.

What’s the difference between a native app and a cross-platform app?
Native apps can only run on one platform because they’ve been specifically written for that app, whether it’s an iOS app written in Objective-C and Swift, or an Android app written in Java and Kotlin. Being written specifically for that platform has its advantages: the code is optimized for the operating system, it can run natively on the device without compiling or a web wrapper, it has direct access to device features, and it gives users the most native-feeling user interface (UI).
Cross-platform apps have an advantage, however: they allow mobile developers to create one source code for an app using common web technologies, which the platform then converts into code for the native environment. The immediate benefits? There’s a much more native app-like performance than a hybrid app. Also, developers can reuse code that’s already been written, letting the platform handle the compiling. This makes it faster and more cost-effective.
So now that we’ve covered how native apps and cross-platform apps differ, let’s look at a popular cross-platform software, Xamarin, and see how its features and capabilities stack up to a native app.

Xamarin is a cross-platform software that generates native apps with platform-specific user interfaces (UI)s. Xamarin compiles the app’s code base and UI code by accessing native APIs for each platform, whether that’s Android, iOS, or Windows. What you get in a totally native experience you do get in file size—Xamarin has some overhead, but the native experience and launch speed users get is nearly unmatched.
Xamarin basics
Programming language: C#—”anything you can do in Objective-C, Swift and Java you can do with C# in Xamarin.”
Platforms: iOS, Android, Windows, Blackberry
Platforms: iOS, Android, Windows, Blackberry
Open-source
Xamarin TestCloud: TestCloud allows you to run automated testing on your apps on over 2,000 devices, and build, test and monitor your app in the cloud after development.
HockeyApp: Xamarin’s mobile DevOps support, which allows you to distribute beta versions, collect live crash reports, get feedback from real users and analyze test coverage.
Xamarin.Forms library: This is how the native UIs are created and rendered using native controls of each platform.
Companies using Xamarin: Slack, GitHub, Foursquare, jetBlue
With native…
Developers have to write one set of native code for each platform, with that platform’s programming language and frameworks. If you want to create native apps for more than one platform, that often means double the work, double the resources, and more time spent updating, patching, and debugging each app in the future. That code is optimized for that platform, but it can run there and only there.

That code is optimized for that platform, but it can run there and only there.
With Xamarin…
A shared code base requires less time and resources. When you’re working with the one, shared C# code base, that code base can be used among the three platforms, leaving the majority of the effort to creating the platform-specific UIs. Think of it like 70% Xamarin code and about 30% native code—and the Xamarin code is reusable with the .Forms library. Note that it can be helpful to have an experienced Xamarin expert who knows their way around the platform to keep code neat and organized.
Apps are easy to update. One of its core benefits is the ability to make updates, changes, and improvements to the app over the lifespan of an app relatively easily. With native, the process is similar, only it’s duplicated for each version of the app.
If you know C#, it’s not hard to learn. C# is a pretty common programming language that many web developers already know, so it doesn’t require learning another platform-specific language and framework. You’ll need to know languages for the native environments—whether that’s Java and Kotlin or Objective-C and Swift.
You’ll get device API access so your app can fully access device features. This means your app can fully access native capabilities, just like a native app. This is one way Xamarin stands out from other cross-platform softwares.
Wondering which route is best for your mobile app?
The best way to approach your mobile app project is usually to consult with a skilled, experienced freelance mobile developer like those you can find on Upwork—someone who will be able to talk through what you’re looking for from your app so you can choose the option that will give you the best results to fit in your scope, budget, and timeline.
