About me

In the last decade I’ve worked on projects for a variety of customers that are displayed above. I’m passionate about conferences and other knowledge sharing initiatives. An example is the development of the Sympose Conference plugin for WordPress. I’ve built various webinar/live video implementations and am experienced with platforms like BuddyPress and LearnDash.

I’m happy to help out with advice on website development, second opinions or actual software development. If you just need a push in the right direction for your project, do not hesitate to contact either.
