Shahzad M.

Your app idea is ready. You just need someone who will actually ship it. I've launched 15+ apps used by over 1 million people. I'm Shahzad, a Senior Android and iOS developer. I have 5+ years of experience building Android apps with Kotlin and Jetpack Compose, from small MVPs to apps with over a million users. On iOS, I build native apps with Swift and SwiftUI. Need one platform or both? You get one developer who takes it from the first screen to the store release. ✅ Top Rated, 100% Job Success ✅ 17 projects completed on Upwork, mostly 5-star ✅ Replies within a few hours ⭐⭐⭐⭐⭐ "Was great working with Shahzad!
