Hi, I'm Jonas. I'm a web developer and work as a freelancer, specializing in developing full-stack websites and web applications customized from CMS to frontend.

Customized Web Design
I strive for beautiful websites and applications that are fully customized, leight-weight, mobile-centered and accessible for everyone. Therefore I usually collaborate with graphic-designers such as:
Soundssss
Apart from web development, I have a passion for electronic music and enjoy creating projects that make noise. Whenever possible, I seek to intertwine sound with web development. Additionally, I co-run a label called "PH17" with SOLARIS, primarily releasing content under my alias, Stanley Schmidt.
Get in touch if you need a web-programmer, I'm also happy to recommend a graphic designer for your project.
