Daniyar Kurmanbayev is a Senior iOS Developer and Mobile Engineer with 6+ years of hands-on experience building, rescuing, and launching production iOS apps, and a broader 9-year software background that spans full-stack delivery. He specializes in native iOS work—Swift, SwiftUI, UIKit, Objective-C, StoreKit 2, in-app purchases, SDKs, and App Store delivery—often modernizing legacy codebases and repairing entitlement/payment flows for existing paid users. Daniyar pairs product-minded engineering with practical prioritization: he focuses on what must be fixed first to stabilize apps, what can wait, and what will reduce maintenance burden after launch. His recent projects include launching a Stripe/Apple Pay marketplace, migrating Objective-C music apps for ~2,500 paid users, and delivering cross-platform safety tracking with background location and geofencing. Comfortable both leading product delivery (RBC) and shipping code, he also brings AI and systems experimentation experience—including prototypes using Nearby Interaction, Multipeer Connectivity, and Rust/UniFFI. Based in Old Toronto, he helps startups and founders turn fragile mobile products into production-ready, monetizable apps.
