Who I am

As you probably already read, my name is Marc, and I live in Kempten (Allgäu).

I'm a computer scientist, specialized in everything that happens on the internet — websites, APIs, SAAS, Apps, Enterprise Applications, and much more.

I am working as a web performance consultant, a web developer, a frontend architect, and as a trainer for developers.

Web Performance Consulting

I am a Web Performance Consultant with a passion for fast sites. I offer web performance audits or analyzes for your companies and workshops for developers or development teams.

Web Performance is still one of the most underrated topics in web development. Even though it can help us, our companies and customers with their online business, make our website more accessible for people with a slow network and has a significant impact on a sustainable internet.

Customer testimonials

  • Since I've been working with Marc Radziwill, my website has been at the forefront of SEO. I wouldn't have thought it possible what page speed, a clean web architecture and continuous page maintenance makes a difference. Thanks to the competent support as web developer, technical consultant and the continuous care/maintenance of the site, I can fully concentrate on content and concentrate the numerous requests :) If there is a problem with the site, I often get it only afterwards, because Marc already took care of it and solved the problem. Many thanks for the competent and reliable cooperation and the uncomplicated, direct line.
