Hire the Best iOS 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.

I’m Rubén Gómez López, a Mobile Team Lead and Software Engineer with over 12 years of experience in mobile development, specializing in both Android and iOS platforms. Throughout my career, I’ve worked primarily with startups, bringing early-stage mobile apps to life and scaling them for market success. I’ve led teams in designing, developing, and launching high-impact mobile apps, including working as the lead on Snorble's app, where I spearheaded a project from the ground up using Flutter, guiding a team of five developers, making key architectural decisions, and implementing agile practices to ensure quality and scalability. My passion lies in creating elegant, scalable mobile solutions, with a focus on utilizing the latest hybrid technologies like Flutter, as well as native iOS (Swift) and Android. My experience includes managing a suite of apps for Employee Network Inc. and contributing to the development of market-reaching apps like Pixable, with almost 10 million active users, and Runator, a social network for runners, where I served as CTO. I thrive in dynamic environments where I can solve complex problems, mentor teams, and drive innovative mobile strategies that align with business goals.

𝟮𝟬+ 𝗺𝗼𝗯𝗶𝗹𝗲 𝗮𝗽𝗽𝘀 𝗯𝘂𝗶𝗹𝘁 𝗮𝗻𝗱 𝘀𝗵𝗶𝗽𝗽𝗲𝗱 𝘄𝗶𝘁𝗵 𝗙𝗹𝘂𝘁𝘁𝗲𝗿. 3+ years industry experience— 𝗲𝘃𝗲𝗿𝘆 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝗳𝗶𝗻𝗶𝘀𝗵𝗲𝗱, 𝗻𝗼𝘁 𝗮𝗯𝗮𝗻𝗱𝗼𝗻𝗲𝗱 𝗵𝗮𝗹𝗳𝘄𝗮𝘆. I'm Ahmed Raza. I work with founders and startups who need mobile app development done properly: an idea turned into something real, on both stores, that doesn't fall apart the first week real users touch it. Most of my work has been under NDA, so I can't drop app names or download numbers here. If you want to see specific examples, I'm happy to walk you through case studies (sanitized where needed) on a call. Technically: Flutter and Dart for the app itself, Firebase or Supabase on the backend, Stripe or RevenueCat for payments and subscriptions, native Swift or Kotlin when a Flutter package genuinely can't do the job which happens less often than most developers claim. I also build AI-powered features into apps when a project calls for it: smart search, recommendations, personalization the kind that fit the product instead of feeling bolted on. If you've got a Figma file, a half-built codebase, or an idea that hasn't been scoped yet, send it over. I'll give you a straight, honest read on timeline and cost before you commit to anything. I only take on work I'm confident I can deliver well. Core Stack: Flutter, Dart, Firebase, Supabase, Swift, Kotlin, REST APIs, Stripe, RevenueCat, Google Maps, Push Notifications, App Store Connect, Google Play Console

🚀 Mobile App Developer with 8+ years building high-performance iOS and Android apps that reach real users and drive real results. I specialize in cross-platform and native development with React Native, Expo, Flutter, FlutterFlow, and Swift - delivering polished, production-ready apps from concept to App Store launch. Before going full-time into mobile development, I worked in digital marketing and e-commerce - so I don't just build apps, I build apps that convert and retain. That means I understand LiveOps, retention mechanics, push notification strategy, onboarding flows, and ASO at a level most developers simply don't. 🔧 WHAT I BUILD ✅ Cross-platform apps with React Native + Expo (single codebase for iOS & Android) ✅ Flutter & FlutterFlow apps - rapid UI development with pixel-perfect results ✅ Native iOS apps in Swift / SwiftUI for performance-critical use cases ✅ Real-time features: WebRTC video/audio & live streaming, live chat, push notifications, geolocation ✅ LiveOps & engagement systems: progression, reward loops, streaks, timed events, leaderboards ✅ Gamification for non-gaming apps - points, badges, levels, quests that measurably lift retention ✅ Video & streaming: HLS playback, watch-state and episode progression, content scheduling ✅ Backend integrations: REST, GraphQL, Firebase, Supabase, AWS Amplify ✅ SDKs: Stripe, RevenueCat, Twilio, Agora, Google Maps, OneSignal, Sentry ✅ App Store & Google Play deployment, legacy refactors, performance tuning, code audits 📈 ENGAGEMENT & LIVEOPS EXPERTISE Where I stand out is building the systems that keep users coming back after install day: → LiveOps tooling: remote config, feature flags, scheduled content drops and timed events - run your app like a live service without shipping a new build → Progression & reward systems tuned with real analytics data → Retention & lifecycle engagement: segmented push campaigns, re-engagement flows, personalisation → Experimentation: A/B testing and staged rollouts with clear success metrics → Real-time & community: WebRTC live video/audio, chat, presence, audience participation I design engagement features around D1/D7/D30 retention, session frequency, and conversion to paid - not just tickets. 💡 HOW I WORK Clear communication, well-structured TypeScript-first code, and relentless attention to detail. I document decisions and keep you in the loop at every milestone. I've worked with startups, scale-ups, and small businesses across the US and Europe - solo or within distributed teams, on greenfield products and messy legacy codebases alike. I'm responsive, deadline-aware, and I treat your app like it's mine. 🛠 TECH STACK Mobile: React Native, Expo, Flutter, FlutterFlow, Swift, SwiftUI State: Redux Toolkit, Zustand, Riverpod, MobX Real-time & Media: WebRTC, Agora, SocketIO, HLS streaming LiveOps & Growth: Firebase Remote Config, feature flags, A/B testing, OneSignal, Amplitude, Mixpanel Backend: Firebase, Supabase, Node.js, REST, GraphQL Data: SQLite, Realm, AsyncStorage, Core Data CI/CD & Testing: GitHub Actions, Fastlane, EAS Build, TestFlight, Jest, Detox, XCTest Design: Figma (wireframes or full specs) 🌍 INDUSTRIES E-commerce | Health & fitness | Streaming & vertical video | Marketplaces | SaaS | Social & community | On-demand | EdTech | FinTech | High-engagement consumer apps 📦 WHY CLIENTS CHOOSE ME → Full ownership from wireframe to live App Store listing → Retention-first mindset: LiveOps, gamification, and engagement loops built in from day one → Strong English, US timezone overlap available → No disappearing acts - consistent updates via Slack/email → Business-aware developer who thinks beyond the ticket Let's build something great together. Send me a message and let's discuss your project. KEYWORDS: React Native developer, Flutter developer, Expo, iOS, Android, Swift, cross-platform app, WebRTC developer, live streaming app, video streaming, LiveOps, gamification, retention mechanics, progression systems, reward loops, A/B testing, remote config, push notifications, Firebase, Supabase, Stripe, RevenueCat, subscriptions, real-time chat, MVP development, app audit, performance optimization

Most businesses waste 3–6 months and $30K–$80K hiring separate web and mobile teams that can't sync properly. I build both — as one integrated system — so you get a single developer who owns the full stack: backend API, web dashboard, and mobile app, all working together from day one. 10+ years. 150+ web apps. 200+ mobile apps shipped. ───────────────────────────── WHAT I BUILD ───────────────────────────── ✦ SaaS Platforms — web admin + mobile app + shared backend ✦ E-commerce — Next.js storefront + mobile app + inventory panel ✦ FinTech — web banking dashboard + mobile payment app ✦ Logistics — fleet management web + driver mobile app ✦ Social Platforms — web interface + iOS/Android + real-time features ───────────────────────────── TECH STACK ───────────────────────────── Mobile → Flutter · React Native · iOS · Android Web → Next.js · React · TypeScript · Tailwind CSS Backend → Node.js · REST/GraphQL · PostgreSQL · Prisma Infra → AWS · Vercel · CI/CD · Docker ───────────────────────────── WHY CLIENTS CHOOSE ME ───────────────────────────── → One developer = no miscommunication between web & mobile teams → Shared API & auth from the start = less rework later → Full ownership from architecture to App Store deployment → Cross-platform expertise = faster delivery, lower cost "Built our entire digital ecosystem — web app, mobile app, admin panel — perfectly integrated." ⭐⭐⭐⭐⭐ ───────────────────────────── GOOD FIT IF YOU NEED: ───────────────────────────── - Web + mobile built together (not bolted on later) - A single technical owner for the whole product - MVP shipped fast without sacrificing architecture - Ongoing maintenance and feature expansion ───────────────────────────── LET'S TALK ───────────────────────────── Send me a message with: → What you're building (web, mobile, or both?) → Your core features and target users → Timeline and budget range I'll reply within a few hours with honest feedback on your stack and a rough scope estimate — no commitment needed.
