I’m an entrepreneur and iOS developer based in San Francisco.

Currently I’m the co-founder of a startup called Kullect, where I built the Kullect iOS app and now work on Shout Photo Messenger.

Before that I ran Take Five Labs where I created mobile apps for companies like Kaplan, Veritas Prep, and the National Parks Service.

I also make the KLCPopup library for iOS, which lets you turn any UIView into a fancy popup with pretty animations.

Sometimes I tweet on Twitter.
