Hire the Best Swift Developers

Most developers build you an app. I build you a product. There's a difference. An app is code that works. A product is something users keep using, and pay for. I know the difference because I've shipped both sides. I built core modules for Traderverse, a social trading platform that scaled to 28,000 users with real-time feeds, live portfolio tracking and Swift Charts. I've also published four of my own apps on the App Store, funded with my own money: Balancio, Just Invoice, Scan IT, and Timey. When you self-publish, you learn fast which decisions actually matter: paywall placement, subscription flows, onboarding, App Store review. What I build: * Native iOS in Swift and SwiftUI (MVVM, SwiftData, Combine, AlarmKit, VisionKit) * Subscriptions and monetization with RevenueCat, StoreKit 2, paywalls, entitlements * Backend and auth using Firebase, Supabase, social sign-in, cross-device sync * Real-time data via WebSockets, live feeds, Swift Charts for financial and analytics UIs * Localization into 5+ languages including Arabic RTL with full UI mirroring * Shipping through Xcode Cloud, TestFlight, App Store Connect, ASO What you can expect: * Conservative estimates. I'd rather quote four weeks and deliver in three * Early warnings when something is at risk, not surprises at handoff * Honest scoping. If a request is outside my strength, I'll say so upfront * Products shipped end to end, from concept through App Store review and ASO I also work in React Native and Flutter for cross-platform projects, and build web SPAs in Vue and React, including Trader Analytics, a live equities dashboard with 80+ KPIs and subscription tiers. Both my Upwork contracts closed at 5.0 with 100% Job Success. Available for a call to talk through what you're building.

🏆 13+ years on iOS and Android, 5,500+ hours, 100% Job Success, Top Rated 🏆 I build AI powered mobile apps in React Native and Expo, plus the API and web dashboard behind them. When the framework runs out I write the native Swift or Kotlin myself. Every cross platform app hits the same wall eventually. The camera needs a frame the library won't hand you. A background task dies the second iOS suspends the app. HealthKit or Bluetooth wants a permission flow no wrapper handles. Or the AI feature you just added makes the list stutter on a 3 year old phone. That's the week your developer tells you React Native can't do that. It usually can. Somebody has to open Xcode and write the module. The second wall is quieter. The app ships, and then nobody can see inside it. No admin screen. No way to answer a support email. No place to read what the AI actually returned. That's when a second contractor gets hired for what was always one product. I help founders and product teams ship one app to both stores, with the API and the dashboard that runs it. Not 3 contractors hoping the other 2 agree. 🏆 "Algene was incredible to work with...he took a thorough look at what my vision was and stepped in with a grounded and disciplined approach." - BarkLens, an AI powered dog health app in React Native and Expo. 5 stars, endorsed Collaborative. 𝗟𝗜𝗩𝗘 𝗢𝗡 𝗧𝗛𝗘 𝗔𝗣𝗣 𝗦𝗧𝗢𝗥𝗘 🏆 Remi by Reflect - an AI powered self reflection app in React Native. 🏆 Offleashd - a social community for pet parents, with AI features, in React Native. 🏆 Break Scroll - my own dopamine detox app, built solo and taken through review. 𝗧𝗛𝗘 𝗕𝗨𝗜𝗟𝗗𝗦 𝗧𝗛𝗔𝗧 𝗟𝗔𝗡𝗗 𝗢𝗡 𝗠𝗬 𝗗𝗘𝗦𝗞 ✔️ AI Features Inside An App That Already Has Users OpenAI, Claude, Gemini, DeepSeek, or Apple's on device models. I shipped the AI winner prediction and the strike heat map inside FX1's MMA app, in Swift and SwiftUI. Live fight data and real time chat ran in the same codebase. A separate React Native contract ran on Apple Intelligence for 82 hours and closed at 5 stars. ✔️ React Native And Expo, One Codebase, Both Stores 434 hours on one React Native contract, plus 3 more on the record. TypeScript, Redux Toolkit, Zustand, React Query, and a build that actually signs. ✔️ The Web Half Of The Same Product The REST or GraphQL API your app talks to, and the React or Next.js dashboard your team runs it from, so support can answer a customer or pull a refund without messaging you first. Node and Express, PostgreSQL, Supabase or Firebase underneath. One person on both sides. The phone and the browser never disagree about what a user is. ✔️ Native Swift, SwiftUI, Kotlin And Java When The Wrapper Won't Do It 889 hours in Swift for one client, across 20 months. Native modules, sensors, camera work. The screens that have to feel native. ✔️ The App That's Built, Live, And Breaking Crashes, memory, a list that stutters, a release that won't go through. One client kept me on fixes for 3 years and 4 months. ✔️ App Store And Google Play, All The Way Through Review TestFlight, App Store Connect, Play Console, signing, permission strings, privacy labels. Plus the resubmission when Apple comes back with a guideline number. 𝗧𝗛𝗘 𝗧𝗢𝗢𝗟𝗕𝗢𝗫 → Mobile: React Native, Expo, Swift, SwiftUI, UIKit, Objective-C, Kotlin, Java, Flutter, TypeScript, Clean Architecture, MVVM → AI: OpenAI, Claude, Gemini, DeepSeek, Ollama, Apple Intelligence, LLM features, AI chatbots, prompt engineering → Web and backend: React, Next.js, JavaScript, Node.js, Express, REST APIs, GraphQL, PostgreSQL, MongoDB, Supabase, Firebase, Tailwind CSS → Release: App Store Connect, Google Play Console, TestFlight, AWS, GCP, CI/CD 𝗧𝗛𝗘 𝗣𝗔𝗥𝗧 𝗖𝗥𝗢𝗦𝗦 𝗣𝗟𝗔𝗧𝗙𝗢𝗥𝗠 𝗗𝗘𝗩𝗦 𝗢𝗨𝗧𝗦𝗢𝗨𝗥𝗖𝗘 🎯 Most React Native developers stop at the bridge. I work the other side of it too, in Swift, SwiftUI, UIKit, Objective-C, Kotlin and Java. A native module is normal work here, not a rewrite quote. ⚡ Philippines, UTC+8. Full overlap with Asia and Australia, mornings for Europe, and a reply inside 4 hours. ✅ 40+ contracts and $100K+ earned on this account, with the endorsements those clients left: Collaborative 10+, Committed to Quality 9+, Clear Communicator 6+ 𝗦𝗘𝗡𝗗 𝗧𝗛𝗘 𝗔𝗣𝗣, 𝗡𝗢𝗧 𝗧𝗛𝗘 𝗕𝗥𝗜𝗘𝗙 Send a repo, a TestFlight build, or just the App Store link, and tell me what's broken or what's missing. You'll get back the 3 things I'd fix first, and whether any of it needs native code. Before we talk money.
