I build mobile apps with the mind of a product owner, the hands of a senior developer and the speed advantage of AI. You are hiring 14+ years of mobile app development, React Native, Flutter, iOS, Android, launch experience, and product judgment focused on making your app work in the real world. I have worked on 500+ mobile app projects across iOS, Android, React Native, Flutter, SaaS platforms, business apps, booking systems, dashboards, portals, and custom digital products. My work is not limited to writing code. I help you think through the product: • what should be built first, • what should be avoided, • where users may get stuck, • how the backend should support growth, • how the app should perform, • how the launch should be handled, • how AI can be used practically without turning the product into hype. My core expertise includes: • React Native mobile app development • Flutter mobile app development • iOS and Android app development • Cross-platform mobile applications • AI-powered mobile app features • OpenAI API and GPT integrations • AI chatbots and smart assistants • AI image analysis and document-processing workflows • SaaS platforms and mobile-first products • Admin dashboards and web portals • Backend development using Node.js, Laravel, Firebase, MySQL, and MongoDB • REST API development and third-party integrations • Payment gateways and subscription systems • Maps, location tracking, chat, push notifications, reports, and analytics • App Store and Play Store launch support • Bug fixing, app rescue, performance optimization, and long-term maintenance My strength is not only development. I help with the complete mobile app lifecycle: • Product planning and feature breakdown • MVP scope definition • UI/UX flow review • Mobile app architecture • Backend and database planning • API structure and integrations • AI feature planning and implementation • Testing, debugging, and performance improvements • App Store and Play Store deployment • Post-launch support and product improvement The truth is simple: AI did not make me a developer. Years of building real apps did. I can help you build a mobile app from scratch, improve an existing app, fix a broken codebase, add AI-powered features, connect backend systems, prepare your app for launch, or support it after release. If you need a developer who can handle both the technical build and the product journey from idea to launch, send me your app details.

Most developers build apps. Very few can also scale them. I do both and I have 100+ live apps on the App Store and Play Store to prove it. If you're a startup or founder, you've likely faced this: → You need AI features that actually work not a ChatGPT wrapper. → Your app is live but installs are flat and you don't know why. → Your subscription system isn't converting high churn, low trials. → You have no idea where your users are coming from or why they drop off. → You've had developers deliver code that works in testing but breaks in production. That's exactly what I fix from first line of code to thousands of installs. APPS I'VE SHIPPED (LIVE ON STORES) → Lush AI : AI beauty & makeup assistant (App Store) → Sculpted : AI looksmaxxing & grooming app (App Store) → FashAI : AI-powered personal style assistant (App Store) → Refine AI : AI photo enhancer & upscaler (App Store) → AI Humanizer (MyWords AI) : human writing tool (App Store) → Freed : AI anxiety & stress relief app (App Store) → MeditaHub : daily meditations & mindfulness (App Store) → QuizMe AI : AI study companion (App Store) → Food Balance : AI nutrition & calorie tracker (App Store) → FaceSwap AVA : AI face swap & avatar creator (Play Store) → Cake Day Gifts : smart birthday reminders (App Store) → AG Fence Pro : professional fencing estimation (App Store) → ToEmployment : AI resume builder & career tool (Web App) 100+ apps shipped. Real users. Real stores. WHAT I BUILD ✔ Flutter & React Native cross-platform iOS & Android apps,clean architecture, production-ready code. ✔ AI Integrations OpenAI, Gemini, vision models, NLP AI features that actually serve your users. ✔ Supabase & Firebase real-time backends, authentication, push notifications, remote config. ✔ RevenueCat Subscriptions trial flows, paywall optimization, churn reduction, subscription analytics. ✔ Full App Store & Play Store Submission screenshots, metadata, compliance, review optimization. MOBILE GROWTH & MARKETING STACK Building the app is only half the job. I handle the full growth stack so your app doesn't just launch it scales. ✔ AppsFlyer Integration SDK setup, attribution tracking, deep linking, postback config, SKAdNetwork for iOS privacy. ✔ Meta & TikTok Ads end-to-end paid user acquisition, campaign structuring, creative testing, budget scaling. ✔ Apple Search Ads keyword research, bid management, discovery & exact match strategies. ✔ ASO keyword strategy, metadata writing, screenshot A/B testing, conversion rate optimization. ✔ Retargeting & Re-engagement deep link campaigns, push strategy, segmented re-engagement funnels. ✔ Growth Reporting weekly dashboards, funnel analysis, install-to-revenue attribution, KPI tracking. WHY CLIENTS CHOOSE ME → 100% Job Success Score every project delivered → Top Rated on Upwork → 100+ apps live on App Store & Play Store → Full-cycle: idea → development → launch → growth → Clean code from day one your codebase won't become a liability six months later → I treat your app like my own product No ghosting. No spaghetti code. No vague timelines. Just clean mobile development built to launch, built to grow. If you want a developer who can build your app AND make sure people actually find it, let's talk. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ [ Flutter | React Native | AI Mobile App Development | OpenAI | Gemini AI | Firebase | Supabase | AppsFlyer | RevenueCat | Subscriptions | Mobile App Marketing | Meta Ads | TikTok Ads | Apple Search Ads | ASO | iOS Development | Android Development | App Store Submission | Attribution Tracking | Mobile Growth | In-App Events | Clean Architecture | SaaS | Flutter Developer ]

Greetings! I am a Mobile App Developer with more than 11 years of experience building applications for iOS and Android. I specialize in React Native development, Flutter development, and native iOS development using Swift. I work with startups, founders, and companies that need reliable mobile software built for real users and real products. Over the years I have helped launch and improve many mobile apps, from early MVP products to large production applications used by thousands of users. My focus is building stable, scalable, and maintainable mobile applications that work smoothly on both iOS and Android. As a React Native developer and Flutter developer, I build cross platform mobile apps that share a strong codebase while still delivering a native user experience. When a project requires deeper platform control, I also develop native iOS apps using Swift, ensuring performance, reliability, and clean architecture. I often join projects where a company needs an experienced mobile developer to build an app from scratch, improve an existing mobile product, or refactor a growing codebase so it can scale properly.
