    Bio

    I have been in the online business since 1998 ranging from building HTML to PHP websites. In 2004 I moved into online marketing and over the years I acquired knowledge in SEO, SEA, Analytics, CRO, UX, and WordPress. In 2012 I started my own online marketing agency where I helped my clients to create more results with their online channels.
    Currently I work as a Context Engineer & AI Developer at Sero.tech and I Freelance as SEO Specialist for a variety of companies.

    Interests

    Marketing Strategy, SEO, SEA, Analytics, CRO, UX, and WordPress.

    WordPress Origin Story

    Started playing around with WordPress 2008/2009 and remember finding a WP version 1.x somewhere floating around. Only after 2012 when I started my own marketing agency did I start working with WordPress more and more. After visiting my first WordPress Meetup in 2014 I soon started helping organize this meetup and visiting others. in 2017 I helped organize WordCamp Utrecht. I still organize WordPress Meetup Utrecht and sometimes contribute as a speaker.
