I had to do with MS SQL databases for the first time in 2000 and looked after these database systems for around seven years. From 2007 to 2019, I was employed as a database administrator and looked after many different SQL servers from medium-sized companies and large corporations from different industries.
Although I have some certificates, I get my insights and knowledge about the SQL Server purely from day-to-day business, reading / following numerous forums/blogs.
I'm not specialized in any topic, but I focus mostly on performance analysis.
Since the end of 2016, I have been the Azure Meetup Hamburg organizer and from April 2017 to June 2018, Cloud and Data Center Management MVP, and since July 2018, Data Platform MVP.
