Über mich

As a certified Symfony Developer and a regular Symfony contributor with a lot of experience gained through various roles while working for several companies in the IT industry, I can support you and your project in many ways.

I love working with legacy code. While I've had the opportunity to work on several legacy projects during my professional life, I've gotten a pretty good understanding of applying techniques like breaking down dependencies, sprouting out new functionality or using test-driven development to add new features and fixing bugs. And I know how important it is to apply all of these techniques by making them minimally invasive one at a time, so code bases get smoothly modernized without breaking any existing functionality.

I also believe that it is very important to share knowledge in different ways. I really enjoy coaching and mentoring developers on various topics by conducting code-reviews or pair-programming sessions and occasionally giving public talks or workshops.
