I build native iOS apps in Swift and SwiftUI โ and I take them all the way to the App Store, not just to a working demo.
iOS developer on NiceOne, the largest online beauty platform in Saudi Arabia and a publicly listed company, where the app serves over 2 million users. I also work on DocUpdate, a HIPAA-compliant e-prescribing app for US clinicians rated 4.8 from 2,700+ reviews, built in SwiftUI with async/await, ConfigCat, Datadog and Bitrise CI/CD.
What I handle:
โข Native iOS development โ Swift, SwiftUI, UIKit, Objective-C
โข Modern stack โ Swift Concurrency (async/await), MVVM, Clean Architecture
โข Backend integration โ Firebase, Firestore, REST APIs, Core Data
โข Payments โ Apple Pay, StoreKit, in-app purchases, payment gateways
โข Arabic/English localization with full right-to-left layout support
โข CI/CD and releases โ Bitrise, Fastlane, TestFlight, App Store Connect
How I work: I send you a build you can actually open โ usually within the first few days โ so you see progress instead of waiting. You get daily updates, clean and documented code, and I stay available after launch for the bugs that only show up with real users.
The apps I build stay alive. Several are still live and maintained years after release โ the oldest since 2017.
Most of my clients come to me with an idea or a half-finished app and need someone who will own it through to release. If that sounds like your project, send me a message with what you're building and I'll tell you honestly whether I'm the right fit.

I build production-ready iOS apps in Swift and SwiftUI for founders and early-stage startups, from empty Xcode project to App Store approval.
iOS engineer at ByteDance on TikTok Shop, 10 completed Upwork contracts, most recently a full SaaS app rebuilt in SwiftUI and shipped at 5.0.
At ByteDance my work covers video performance optimization, scalable mobile architecture, creator-commerce features, analytics attribution, and production stability for platforms used by millions of people daily. Before that I was at Tokopedia, one of Indonesia's largest tech companies, working on high-impact commerce features and internal platform tooling.
What I bring to a project:
โข Native iOS: Swift, SwiftUI, UIKit
โข Production architecture: MVVM, Clean Architecture, SOLID
โข StoreKit subscriptions and monetization flows
โข AVPlayer, video streaming, realtime UI
โข Smooth animations and performance optimization
โข REST and GraphQL APIs
โข Firebase, Supabase, analytics and attribution SDKs
โข App Store submission and rejection recovery
โข Debugging complex inherited codebases
I am especially strong at:
โข Taking an idea or a Figma file to a shipped, stable v1
โข Turning unfinished or unstable apps into production-ready ones
โข Translating designs into pixel-perfect native UI
โข Working independently with clear communication and fast iteration
Recent work includes streaming and subscription apps, AI-powered consumer apps, real-time messaging apps, SaaS dashboards, custom charting and financial UI, and App Store rescue projects.
I am not an agency. You work directly with me as the engineer building your product, which means faster communication, better technical alignment, and one person accountable for the result.
If you need someone who can think past the code and help ship a stable, scalable app, let's talk.
