Łukasz Pyrzyk is a Polish .NET engineer and one of the contributors to the Async Expert course on advanced .NET asynchronous programming. He works alongside Konrad Kokosa and Szymon Kulec on the Dotnetos training platform, focused entirely on the deep performance side of .NET.
His CourseFlix listing carries Async Expert — a deep dive into the async/await model in .NET, covering the synchronisation context, ConfigureAwait, the thread-pool interactions, and the production-debugging patterns for async-heavy code.
Material is paid and aimed at senior .NET developers working on performance-critical applications. For broader content, see CourseFlix's C# category page.
