Hello, ...

my name is ...



How can I help you?

Web Design

For the most part I use Bootstrap and Tailwind. I follow mobile first approach and focus on responsive layouts. Sometimes I like to dabble in some advanced CSS-Features, such as keyframe animations


My favourite frontend-frameworks to work with are ReactJS und VueJS. I am also familiar with jQuery, but I do not use it that often anymore


I am primarily focused on REST-APis. My main technologies are NodeJS & NestJS, Laravel and Python Flask. They are my favourite ones.

Highly-passionated Fullstack-Web-Developer

As someone who loves understanding complex concepts and has a scientific background(B.Sc Chemical Biology, TU Dortmund), it was just a matter of time to find out how much I love programming.
