Jan Schädlich

Wuppertal, Germany

Software Developer, Freelance


Jan is a freelance Software Developer with 15+ years of experience primarily focussed on PHP and Symfony development.

He is 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.

He also loves working with legacy code. While he's had the opportunity to work on several legacy projects during his professional life, he's 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 he knows how important it is to apply all of these techniques by making them minimally invasive one at a time, so code bases get smoothly modernised without breaking any existing functionality.

He believes that it is very important to share knowledge in different ways. And because he really enjoys coaching and mentoring developers on various topics, he likes to conduct code-reviews or pair-programming sessions and occasionally gives public talks or workshops.
