    I have designed and completed many iOS/Swift, Unity/C#, React Native/Javascript, and Flutter/Dart-based apps as a sole, lead, or co-developer and published them on the Apple App Store and Google Play Stores. As a contractor for NASA, I published a Unity/C# iOS/Android augmented reality app for their Visitor Center in Goddard, Maryland, called "WeatherSats AR." I am currently working on multiple contracts in Native iOS, Android, and Unity. On the backend, my expertise is in Firebase, Firebase Functions, and now Microsoft Azure. I co-founded two iOS startup companies with other developers. One is a social media app for craft beer, and the other is a SwiftUI animation-based app where you can draw a multiple-choice question animation and share it with and challenge other users. I have a B.S. in computer science from Rutgers University in 2004, graduating with a 4.0 GPA.
