Sarah has worked as both an iOS and Android developer for 7 years. She’s written Objective-C before ARC existed (and is happy to have the chance to get her hands dirty with Swift and Kotlin these days). She’s released a handful of popular consumer iOS applications, worked on embedded software making modifications to AOSP, and has created a few mobile SDKs. She enjoys solving hard problems and making intuitive, performant, and thoroughly tested software. She’s also a proponent of open source.
