Hi I'm Sebastian. Freelance IT-Consultant.

I'm a consultant in Karlsruhe, Germany for the architecture and development of web applications and technical SEO. 
Usually I work with systems based mostly on Neos CMS and sometimes TYPO3

My focus is on customizing applications to the processes and needs of the users to increase satisfaction and output of the people working with those systems. This includes a focus on semantic data and usability.

As part of the Neos CMS core team I'm actively involved in improving the system continuously to new requirements of the ever evolving web business. You can learn more about my work from my presentations or my Open Source contributions.

I would love to hear from you if you need help in your project or need support your team. I work with customers inside and outside of Germany.

Team work

Working with people is just more fun and you can achieve things you never could do alone.

That's why I'm part of the team that develops the Open Source CMS Neos. To meet with brilliant people and to build something together that's bigger that what each of us contributes.

I also worked at agencies as Product Owner & Certified Scrum Master with diverse teams of up to 10 members.

Web development

I started developing websites when I was 12 years old. I never stopped. Now my focus is on PHP based Content Management Systems like Neos CMS and the ever changing field of technical SEO.

But what I provide includes usually everything from setting up servers, continuous integration pipelines, integration, front-end development and more. 

Other technologies I worked with include Java, ReactJS, jQuery, Python.
