    I fix overseas mistakes. Seriously I am appalled by people who think cheap = good. In the AI space I led the development team at CAMFIND (two million downloads) and TAPTAPSEE which uses AI for image recognition and now image captioning in real time.

I have excellent references and am local. I have several apps that have crossed the 100k+ download threshold and at least three that are 1Million+. I do not outsource overseas, and I am available to meet in the SoCal area as needed. I will work with you from inception of your app idea to launch on the app store or I can solve bug fixes as well. Hire me if you are looking for a serious person who will bring a CTO mentality of getting things done, someone with over 20+ years of problem-solving. Please do not let my hourly rate frighten you (it is there to eliminate non-serious offers). My skills are - Proficient with SwiftUI as well as React Native/Flutter to create hybrid or cross platform apps - iPhone,iPad, WatchKit App Development with SwiftUI, Objective C and Swift/XCode. - Android development with Android Studio and Kotlin -Streaming with MUX, Agora, Wowzaa - Bluetooth Low Energy, iBeacon - Integration of PayPal or Stripe SDK - Integration of Barcode scan/WalletPasses - Core Animation - Push Notification (APNS, GCM) - Storyboard, AutoLayout - iOS Keyboard Customization - Integrating in-app purchase - Integrating iAd and Admob - UI design of iOS and Android app - Video/Audio processing - Google Map Service, Apple Map Service, Geo Location - Camera/Photo manipulation stitching - Chatting by XMPP Framework - Callkit (Voip for apps) - Managing databases (MONGO, NoSQL, SQLite, Core-Data Model) - Working with Github, Bitbucket - Integration of Social Networking (Facebook, Twitter, Instagram, Youtube...) - Video/Audio Streaming, Video Editing, Decoding/Encoding -NodeJS -Mongo/PostGres - React.

    Extensive success developing on the iOS platform for personal projects, individual clients, and startups. My background in tech started over 5 years ago as a high-schooler customizing Shopify sites for my e-commerce ventures. I would then go all in on iOS development in early 2021 to bring my ideas to life through the iOS platform. Today, my main focus is still on personal projects while contracting in the background. With proficiency in Swift and SwiftUI, here is what I can do for you: - Build a modern application from scratch - Revive, update or fix existing applications - Integrate new or existing applications into popular back-ends like Firebase - Get previously stalled app development efforts to the finish line - Consult on feature possibilities, App Store Connect, etc. My process: 1. Briefing / Discussions 2. Research 3. Design 4. Integrate 5. Revise 6. Release I work with the most fluent and up-to-date languages/frameworks in order to provide a rich and fresh user experience. My most commonly used tech stack is Swift, SwiftUI, and Firebase. Recently, I have been working with AVFoundation to create custom camera modules for personal and client applications.
