My name is Jean Pierre Kolb. My areas of expertise include design and conception, marketing and SEO, Linux, servers and networks, security and data protection as well as consulting, customer care, management and development.

I was already working as a media designer, system administrator and network administrator, IT and security consultant as well as developer for agencies, retailers, trade, industry, public authorities and associations.

I have been working in these areas since 1996 and for some time since 1999 under the name „JPK Commerce“. Besides a small overview of my skills you will also find further contact information on my site.

* Since the beginning of 2016 I have been working for „creationell® – die Werbeagentur“. I take on challenging tasks there and look after a large number of customers and projects.
