Full Name Patrick Kevin de Ritter
Date of birth March 1st in Rotterdam
Location Leiden, the Netherlands

I am a driven and ambitious Cloud & Mobility specialist with 5 years of experience in deploying and administration of RDS, Citrix, Office 365 and MDM solutions, based in Leiden, the Netherlands, where I live with my partner of 7 years.

I have worked in IT since 2008, after I stopped pursuing my Bachelor of Computer Science in college. I wanted to stop learning from books and to start doing what I like: working with computers. After more than 10 years in this line of work, I have acquired my knowledge by doing and building on the job as well as off work, and have specialized myself in cloud productivity and mobility solutions.

Current and former co-workers and relations describe me as resourceful, persistent and passionate about the technologies I work with. My other qualities are out-of-the-box thinking and my joy in teaching others about what I do.

I do charity and pro-bono work for several local and rural media outlets via the CyberMediaWorld foundation. We give training to young and talented audiovisual presenters and staff as well as providing technical advice to management and technical staff on achieving top-grade quality on a small budget.

When I’m off work, I love to cook, and discover music. I like to play squash and tennis, as well as a plethora of competitive and leisure video games.
