Rob is a dedicated problem solver who has been developing financial systems on the .NET platform since 2006. Optimizing relational database queries comes naturally to him. He is a very pragmatic programmer who prefers function over fads in software tool choices and a good communicator who prides himself on his ability to positively affect morale.
