Christoffer Hedgate

I work in Lund, Sweden, at a company called Apptus Technologies. Apptus are specialized in database research and consulting, including development of search engines. Most of the time I work with SQL Server as an architect, administrator and developer, but I have also done some work with other DBMS such as Oracle and TimesTen. I also do some programming, mainly in Visual Basic, C# and Java (plus a couple of scripting languages).

I am also the co-owner of sql.nu (http://www.sql.nu/) where you can find more articles from me.
