My name is Kamil Nowinski and I'm the founder & owner of SQLPlayer blog.
I'm Microsoft Data Platform MVP, MCSE. Senior Data Engineer, data geek and friend of Redgate. I speak at user groups and conferences across Europe. Love #SQLfamily and Community around Microsoft Data Platform - that's why my podcast is called "Ask SQL Family" where I talk to well-known and valued specialists in the industry (including Microsoft employees).
