I am primarily a .Net and Java developer, but I also do plenty of database design/development/management (MSSQL & Oracle) as well. I have more practical experience (7 years) DBA-ing MSSQL Server. I have been delving more and more into the Oracle realm, as I have completed an Oracle DBA class in graduate school. Lately at work I have been develop/DBA-ing for a DSE/Cassandra cluster.
