Curt Clifton

Curt Clifton is a software developer with the Omni Group, where he primarily works on OmniFocus for Mac and iOS. Curt came to the Omni Group from Rose-Hulman Institute of Technology, where he was an associate professor of Computer Science and Software Engineering.

Curt blogs occasionally at curtclifton.net. When not programming or writing, Curt can be found on the roads and trails around Seattle wearing out another pair of running shoes or hiking boots.
