Welcome to Holger's Code!

I'm Holger, a freelance software developer with a passion for solving complex challenges. With a Master's in Computer Science and a PhD in Mechanical Engineering, I bring a rigorous, analytical mindset to every project. As a long-standing Embarcadero MVP with over 30 years of specialization in Delphi, I am available for hire to bring that deep, recognized expertise to your project.

My key service today is helping businesses bridge the gap between desktop and web. I specialize in migrating powerful Delphi applications to modern, responsive web platforms using Next.js, React, and TypeScript. Whether you need expert assistance on a legacy project or a partner to guide your migration to the web, I have the skills to ensure your success.

Explore my books, articles, and courses to see my expertise in action, and contact me when you're ready to start building. I am fluent in both German and English.

Let's create something amazing together!
