Stop looking for just a coder. Hire a mobile product partner who can turn complex ideas into polished, scalable mobile apps. 🚀
Building a mobile app is an investment. You need someone who understands product decisions, deadlines, business logic, platform guidelines, AI workflows, backend architecture, and long-term maintainability — not just someone who writes code.
I specialize in building native iOS apps with Swift, SwiftUI, UIKit, clean architecture, AI integrations, and production-ready backend connections. My strongest focus is iOS, but I also build cross-platform apps with Flutter and can support React Native projects when speed-to-market and shared codebases are the right business choice.
Whether you need an AI-powered productivity tool, a subscription-based consumer app, a fintech dashboard, a marketplace, a chatbot, an internal automation system, or a complex real-time mobile platform, I help turn difficult requirements into smooth, reliable, production-ready products.
✅ Why clients trust me
• Top Rated on Upwork with 100% Job Success
• $20K+ earned and 20+ completed projects
• 20+ apps developed, including 10+ live on the App Store
• Strong product mindset: I build what matters, not just what is written in a task list
• Clear communication, fast iteration, and no disappearing mid-project
• App Store-ready quality: privacy, edge cases, review risks, subscriptions, and release flow handled properly
• Clean, scalable architecture so your app does not collapse after version one
🛠️ What I can help you build:
📱 Native iOS apps
Swift, SwiftUI, UIKit, MVVM, async/await, Combine, StoreKit, widgets, App Intents, Live Activities, push notifications, and App Store delivery.
💙 Cross-platform mobile apps
Flutter apps for iOS and Android, plus React Native support for existing apps, MVPs, and startup products that need faster multi-platform delivery.
🤖 AI-powered apps
OpenAI, Claude, Gemini, AI chat, AI agents, structured outputs, image analysis, OCR, voice AI, speech-to-text, text-to-speech, smart workflows, and AI copilots inside mobile or web products.
⚙️ AI automations and business tools
AI business agents, internal dashboards, CRM-style workflows, document automation, reporting tools, notification systems, admin panels, and API-based process automation.
🎨 High-quality UI implementation
Pixel-perfect Figma to mobile implementation with smooth animations, haptics, dark mode, responsive layouts, onboarding flows, paywalls, and polished product details.
🌐 Backend and integrations
Firebase, Supabase, authentication, databases, storage, real-time features, REST APIs, serverless functions, admin dashboards, payments, and third-party integrations.
💳 Payments and subscriptions
RevenueCat, StoreKit 2, Stripe, in-app purchases, entitlement logic, restore purchases, Apple review compliance, and subscription lifecycle flows.
🚀 Launch, QA, and production support
Performance optimization, crash fixing, refactoring, TestFlight builds, App Store submission, Google Play support, bug fixing, analytics, and release readiness.
My technical stack includes Swift, SwiftUI, UIKit, Flutter, Dart, React Native, Firebase, Supabase, REST APIs, OpenAI API, Claude, Gemini, StoreKit, RevenueCat, Stripe, APNs, FCM, Git, TestFlight, App Store Connect, and Google Play Console.
I handle the full product cycle: planning, architecture, UI implementation, backend integration, AI features, testing, release, and post-launch improvements.
