Professional Experience
I started my professional career in 2005, however I wrote the first line of code in 1998 when I was ten. Hence I already struggled with Internet Explorer 4. I will bring 20 years of web-development experience and passion to your project!

e.solutions GmbH
I co-created and performed a so called "Bootcamp" which was used for an company-internal workshop to train employees for Angular.
The bootcamp was an intensive training which spanned over ten weeks and was splitted into different segments from VanillaJS, plain CSS + BEM, HTML5, and deep insights about browser rendering to different Angular topics covering RxJS, real-time applications, application architecture, and testing.
After a final practice task the team was ready to join the real-world project.
Due to regular exchange with the product teams we tailored the course topics to be as close as possible to the final tech-stack.
I managed about ten bootcamps. Each for ten weeks with six to ten attendees.
