Virtual CTO | Skilled Mobile App Dev Consultant - React Native SwiftUI

I can take your best idea and turn it into an app on the Apple App Store and Google Play Store, or build that feature that your users have been asking for for months. I can built iOS apps using the latest technology (Swift, SwiftUI, Combine) or cross platform apps using Typescript and React Native. I have 10+ years of experience developing with Swift. I specialize in building realtime data driven iOS apps, building amazing UI/UX (with user focused design and awesome animations), as well as advanced architecture design. Interested in building apps for Apple's new Vision Pro? With my extensive background in Apple technology, I have experience with all of the libraries and technologies required to build apps for visionOS / xrOS including RealityKit, ARKit, SwiftUI and many more. I can turn your existing iOS app into a spacial experience ready for visionOS, or I can build you a new app from the ground up designed for the Vision Pro. If you can imagine it, I can build it. Are you looking to bring NFTs and crypto features into your mobile app? I believe web3 is the future and we need better apps for users. I specialize in web3 integrations for mobile apps. Whether it's supporting NFTs, crypto payments, digital signatures and proof of ownership, or simply consulting you on what is possible, I am here to help. App Security is a strength of mine, as I have years of jailbreaking experience. I know how to protect your apps against runtime code injection, Objective-C runtime method swizzling, Man-in-the-middle attacks, as well as jailbreak detection. I'd love to hear about your project! Send me a message and let's talk about it.
