A career timeline built from the work history available for this profile.

Senior Ios Developer

San Francisco, Ca, Us

I am a senior member of the TripIt iOS Development team - working full time to keep those five star reviews flowing in. In addition to everyday feature development and bug fixing across both iPad and iPhone versions of the app, I have taken the lead in various architectural overhauls of this time-tested codebase. I must say - I love this job! I work with great people on a great app that customers love and I have the opportunity to stay current and explore which is exactly what I want to be doing. I take pride in my work and that means making it look good, making something that users love to use and keeping up with new iOS features. In addition to working on the app itself, I have been fortunate enough to develop the following iOS App Extensions:• TripIt Apple Watch App (released same day as Apple Watch 1.0)• TripIt iMessage extension (released same day as iOS10)• TripIt Today extensionWhile a lot of the application code was written in Objective-C, I was an early proponent of and pressed the usage of the Swift language. Much of my work here has been in Swift or a mixture of Objective-C and Swift.
