He was raised in Oklahoma and Texas, and as he writes in his Medium article, he is currently a software engineer at Microsoft working on Wunderlist, and a photographer. He is a resident of Berlin.

In 2005 Davidson turned his programming interests and attention in the direction of Ruby on Rails. In tandem with well-known Rails guru Mike Clark, he designed and built some of the most complex and robust early Rails applications.[citation needed]

Starting in 2005, Duncan added photography to his other professional focuses.[1] He has served as the primary event photographer at several high-profile technology conferences. Since 2009 he has been the main stage photographer for TED conferences,[2] photographing every TED and TEDGlobal event. In 2010, Duncan was the photographer for the Mission Blue Voyage in the Galapagos Islands and led the TEDxOilSpill Expedition in the Gulf of Mexico. Davidson is also known for his artistic travel photos, often with an eye for architectural details, a clear reference to his university studies in architecture.

He is co-founder and co-owner (along with Greg Koenig) of Luma Labs, a small company based in Portland, OR focused on making high quality camera accessories.
