Description

Fullstack Web Developer with a passion for clean code and quality standards.

I have been supporting small and large companies for 19 years, both as a permanent employee and as a self-employed individual.

My current focus is on backend development (PHP, MySQL, DBAL, API, SOAP, REST, PHPUnit). In the past, I also did frontend development (HTML5, CSS3, Javascript, VueJS, jQuery, responsive design, Bootstrap). At least HTML5, CSS3, Javascript, jQuery are part of my daily practice. I always use static code analysis (phpcs, phpmd, phpstan) to achieve a minimum level of quality. Furthermore, I am an advocate of code that is tested as extensively as possible and use tools like PHPUnit, Behat, codeception and Selenium, cypress, playwright. I personally use a Linux machine, which helps me to assist with the administration of server systems. I am familiar with Gitlab, GitHub and Ansible for setting up and maintaining CI pipelines.

I see myself as an advocate of the Agile Manifesto. To support each other optimally in project management, I have implemented some projects with Scrum or Kanban.
