Dirk Holtwick

Ruhr Valley, Germany

My goal is to develop appealing applications for communication and knowledge storage while having a strong focus on users privacy and data ownership. Many years of experience in developing software products for large companies with a broad audience helps me to reach this goal.

With your support I will have the freedom to produce these applications and frameworks as open source.

Independent developers can make a difference to protect your privacy and individuality.

If you like to learn more about my projects follow me @holtwick and @apperdeck and visit my blog.
