Summary
🤩
Rockstar🎓
Top SchoolJonathan Pryor is a seasoned software engineer and engineering manager with 18 years of experience specializing in .NET, C#, and cross-language interoperability between C#, Java, C, and C++ for mobile platforms. He was the principal architect behind .NET for Android and key projects like dotnet/java-interop and dotnet/android, enabling C# apps to run seamlessly on Android via JNI and contributing thousands of commits across dotnet and Mono repositories. As a long-time manager at Xamarin and Microsoft he led distributed teams across many timezones, drove the Mono-to-.NET runtime migration, improved build/deploy tooling, and delivered performance and debugging enhancements that materially improved developer productivity and .NET MAUI’s Android support. Jonathan combines deep runtime and native-code expertise with practical tooling and documentation work—he wrote an Irony-based parser to transform Javadoc into C# XML docs and championed a culture of “useful commit messages” to preserve design intent. Now contracting for Uno Platform, he’s exploring .NET 10 previews and NativeAOT on Android, continuing to bridge runtime innovation with pragmatic engineering. Based in Richmond, VA, he’s the kind of engineer who thinks as much about maintainability and rituals (commit messages) as about low-level correctness.
