Drupal expert at your service

Acquia Certified Developer

Drupal is one of the most used content management systems today. Thanks to many years of experience, I will deliver it to you perfectly configured, without ballast, equipped with the necessary modules and with a custom look theme according to the graphic design. I can also handle customized modules.
Drupal 10

I know Drupal deeply

Drupal Administration
  • I built my first website on Drupal in late 2004 and early 2005. In my many years of experience I have built small websites, medium sized magazines and large portals and e-marketplaces. Thanks to Drupal’s modularity, I am able to build a site that is easy to administer and will grow with your company’s needs.
  • As the first developer in the Czech Republic, I received the Acquia Certified Developer certification for Drupal 11. Previously, I also received the Acquia Site Builder and Developer Certifications for older versions of Drupal 7, 8, 9, and 10.
  • For each project, I create a customized design theme based on a prepared graphic design. I will ensure that your website achieves best results in Google Core Web Vitals, loads fast and is comfortable to navigate.
  • Need a specific solution for which there are no community modules? Creating customized modules has never been an obstacle for me. I can handle linking to other applications, data imports and other challenges.

Complete websites and
Drupal consulting

I am able to implement any type of website for you with this content management system. I have been working with Drupal since 2005, I also wrote the first Czech book about Drupal. You can find a number of websites I have built on this system in references.

If you are building a website on Drupal on your own, we can arrange for technical supervision, analysis of the solution used or consulting on partial parts of the site or module development.

Drupal has been training other web developers for many years. I would be happy to meet you at one of the training sessions. I will teach you Drupal on the administrative side, introduce you to module development and appearance themes.

Drupal knowledge backed by experience

In 2009, long before the official Drupal certifications began, I confirmed my knowledge with a test from ExpertRating. This verified my knowledge of Drupal 6.

Since mid-May 2014, I have been a certified developer working with Drupal 7 (the first and one of the few in the Czech Republic). The exam and designation from the creators of Drupal, Acquia Certified Developer, says that its holder is able to cover the entire range of Drupal issues, whether it concerns work with administration, or the development of modules and appearance themes.

In April 2017, I was the first in the Czech Republic to successfully confirm my knowledge of Drupal 8 by completing the certification process for Acquia Certified Site Builder. In December 2020, I successfully completed the same certification for Drupal 9. I was one of the first in Europe to obtain the certification for Drupal 10. Similarly, I am continuing with my Drupal 11 certification.

I am also an individual member of the Drupal Association and contribute regularly to its development.
