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.
