I design simple apps.
I figure out the best way to display data and make the app easy to understand by the user. I'll make a clickable prototype for Your app with Invisionapp, so you can actually test it with dummy data and app screenshots before we move to writing the app code.
I write beautiful code.
I run Xcode software and delve into the code of Swift programming language. When finished You'll have a fresh fully working/living/breathing native app in your iPhone or iPad via Testflight, ready to be launched on Apple AppStore.
