I’m a firm believer that the most effective way for us to improve as software engineers is to build software. However, I still publish free articles and videos to help supplement learning. And for that same reason, I’ll be offering courses of different kinds here. If you are using these materials to supplement your efforts in building things, then I think you’re on the right track!
Dometrain Courses
These are software engineering career courses and programming courses that are hosted on Dometrain. Dometrain courses are paid for and generally much longer and more in-depth than the other courses I will offer here. Nick Chapsas has created an *awesome* platform for getting some of the most experienced software engineers and software architects together to teach you about all of their experiences.
I’m proud to be a Dometrain course author and will happily continue to support the platform!

C# and DotNet Courses
The most complete path to learning modern C# -- the 'Getting Started: C#' and 'Deep Dive: C#' courses bundled together at a 20% discount. Covers everything from your very first C# program through advanced patterns like async/await, LINQ, generics, and object-oriented design. Ideal for beginners to intermediate developers who want a rock-solid foundation in C#.
Perfect for anyone new to programming or switching from another language, this course teaches everything you need to start writing C# code from scratch. Using real examples and hands-on exercises, you will build a solid foundation in the language that powers Microsoft Azure, enterprise software, and countless production systems worldwide. No prior programming experience required.
Takes you beyond the basics and into the features that professional C# developers rely on every day. Covering OOP patterns, LINQ, generics, delegates, streams, and the full async/await model, this course is built for developers who understand C# fundamentals and want to confidently tackle real-world production codebases. Prerequisite: Getting Started: C# or equivalent experience.
Reflection is what powers dependency injection, serialization, ORMs, and countless .NET frameworks -- yet most developers use it without fully understanding it. This course teaches you how to correctly inspect and invoke types at runtime, scan assemblies, work with attributes, and use reflection with generics. Knowing how to use this tool responsibly will make you a significantly more capable .NET developer.
Learn practical techniques for improving any C# codebase -- making it more efficient, readable, and maintainable without changing its external behavior. Using real-world examples, you will learn when and how to apply modern refactoring patterns including extract method, dependency injection, and the strangler fig pattern for larger rewrites. A must-have course for any C# developer working on a production codebase.
