👨 About Me 👨
Hi, I’m Zoran, I have more than 25 years of experience as a software developer, architect, team lead, and more. I have been programming in C# since its inception in the early 2000s. Since 2017 I have started publishing professional video courses at Pluralsight and Udemy and by this point, there are over 100 hours of the highest-quality videos you can watch on those platforms. On my YouTube channel, you can find shorter video forms focused on clarifying practical issues in coding, design, and architecture of .NET applications.❤️

Transforming working code into a reusable library requires deliberate design decisions. Key steps include choosing descriptive names, ensuring API consistency, introducing clear concepts (like repository patterns), creating abstractions to hide implementation details, and organizing code with nested namespaces. The tutorial demonstrates refactoring EF Core code for immutable entities, showing how to evolve from inconsistent extension methods to a clean, interface-based library with intuitive method names and minimal surface area.
