I have experience developing iOS apps involving AR kit (augment reality), MLKit and have integrated webkit webview so that web apps can run inside the app. I am familiar with iOS native UI, and able to integrate other frameworks that work with native UI. I know swift and objective c as with many other languages. Javascript of course. I also build web services that drive these apps in aws and google cloud, though I wouldn't be opposed to other cloud providers. Services built from scratch is something I can work with as well. CI/CD in gitlab and github is also something I am familiar with when infrastructure as code is desired for both iOS apps and web services. Same for android.
