I have experience developing android apps involving AR core (augment reality), MLKit and have integrated webkit webview so that web apps can run inside the app. I am familiar with android's material design, and vanilla UI. I know kotlin and java 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 android apps and web services. Same for iOS.
