Project History
Other Words
https://otherwords.appOther Words is a Catch Phrase party game for iPhone. Unlike other group word games, it is not pass-and-play. Everyone plays on their own device. I used Apple's Network framework for keeping everyone in sync.
Haiku by BAF
From 2015 to 2018, I was the lead developer for the Haiku by BAF app. Haiku is a line of residential ceiling fans. The app can be used to control the ceiling fan, light, and wall controller, as well as to update the firmware.
