I have worked with Sitecore for 15+ years now. First with a partner, doing Sitecore projects, and for the past 10+ years, working directly for Sitecore as a sales engineer, in the Sitecore Emerging and Nordics market sales team. Fun fact; I have very much enjoyed working with XSLT in the old days, and sometimes dreams myself back to those non-complicated days, with single server setups and entire pages being rendered directly with XSLT ;)
