My name is Daniel Simelka and I am located in Schwerte, NRW, Germany. I´m working in the IT industry since 2003, so I have  round about 14 years of experience. I started as an Administrator dealing with a lot of topic. But over the year I focused more and more on VMware and since 2012 I do it every day as a consultant.

I am currently a IT Senoir Expert working for Computacenter AG & Co. oHG in Germany. I primarily focus on Datacenter Infrastructur with vSphere and vSAN within the Software Defined Datacenter (SDDC). I also do/did some HCI things like PernixData, Nutanix or Simplivity. Recently I started with VMware NSX so the future will be interesting.
