About me 👨‍💻

Pragmatic engineering, strong foundations, and a passion for building things that last.

I’m a senior .NET engineer with a long background in cross-platform development, having worked through WPF, Silverlight, Windows Mobile, Xamarin, and .NET MAUI. This gives me a deep understanding of how platforms and products evolve over time.

Today I focus on .NET MAUI, ASP.NET Core, and Azure, designing systems that scale, perform well, and are easy to maintain. I value clarity over cleverness and pragmatic decisions over trends.

I also maintain open-source libraries used by the .NET community, with special attention to developer experience, clean APIs, and solid documentation.

My journey 🧭

A short, human-friendly view of how I got here.

🏗 Foundations

Started with desktop applications for banking and public institutions, building strong engineering fundamentals with C#, WPF, and Silverlight.

📱 Mobile

Specialized in mobile development with Windows Mobile, Xamarin Native, Xamarin.Forms, and now .NET MAUI — including migrations and frameworks.

☁️ Cloud

Designed and built Azure-backed platforms combining mobile apps, web frontends, APIs, and background services with CI/CD and quality gates.

❤️ Open source

Personal interests 🧩

A few things that keep me balanced and energized outside of work.

Outside of software development, I spend a good amount of time around the water. I play water polo and regularly swim, which helps me stay focused, disciplined, and mentally refreshed.

I also enjoy the multi-discipline challenge of triathlon training, where long-term consistency and incremental progress matter more than quick wins.

Beyond sports, I’m deeply interested in open-source development — maintaining libraries, improving documentation, and contributing back to the developer community whenever I can.
