Prayag G.

I build and improve native iOS apps using Swift, SwiftUI, and UIKit—from MVP development to App Store launch. With 8+ years in software development, including 7+ years in iOS, I specialize in AI features, subscriptions, and reliable mobile experiences. Need to launch an iPhone app, finish an existing product, or add features to a live application? I help founders, startups, and product teams turn requirements into maintainable, production-ready iOS apps. My experience includes 17+ mobile products across AI, logistics, healthcare, education, e-commerce, and productivity—including three production AI apps and two applications built and published independently.
