About Maik

Do you need support with Typo3 – development, migration, administration, or maintenance of your website? That's exactly what I'm here for.
With over 25 years of experience in web and PHP development – 11 of which were self-employed and since 2011 as a frontend/backend developer with a focus on Typo3 – I bring in-depth practical knowledge that other freelancers rarely offer at this depth.

Typical projects I undertake:

  • Setting up, expanding, or migrating Typo3 websites
  • Bug fixes, updates, and ongoing support for existing sites
  • Full-stack web development with PHP, JavaScript, Python, HTML/CSS
  • Small individual tools and scripts as needed

I work part-time, in the evenings and on weekends – remotely, reliably, and without agency overhead. Ideal for clients looking for targeted, competent support rather than a full-time agency.

Implementation of individual web projects for corporate clients – from conception through CMS customizations to content integration and ongoing technical support. Focus on Typo3 extensions, frontend templating with HTML/CSS/JavaScript, and integration with backend services. I place particular emphasis on clean code quality, cross-device compatibility, and maintainable solutions that run reliably even after years.
