Have an app idea, or an app that is stuck? I turn it into a working product: planned, designed, built and launched on iOS, Android and the web. Top Rated on Upwork | $100K+ earned | 260+ jobs | 160+ client reviews I'm a full-stack mobile app developer working with Flutter, React Native, React, Node.js and MongoDB. I handle the app, the backend, the database and the admin panel as one project. ------------ HOW YOUR PROJECT MOVES FROM IDEA TO LAUNCH Step 1. Plan: we agree on the features of the first version (MVP), the budget and the milestones. Fixed price or hourly, your choice; for fixed price you pay only when a milestone is approved. Step 2. Design: screens and user flow, from your Figma file or from scratch. Step 3. Build: the mobile app, backend and admin panel. At every milestone you get a working build on your own phone (TestFlight or APK) and a short screen recording of each finished feature. Step 4. Launch: real-device testing, deployment, App Store and Google Play submission, including fixing rejections. Step 5. Support: 30 days of free bug fixes after launch, then updates and new features when you need them. Progress message every working day; I work until late evening Pakistan time and overlap with US and European hours. ------------ BOOK A CONSULTATION Not sure where to start? Book a 30- or 60-minute consultation from my profile. In the call we will: ✔ Review and refine your idea, or go through your existing mobile app ✔ Choose the right technology for your budget ✔ Estimate the build cost and the running costs as your users grow ✔ Plan the first version and its milestones Within 24 hours you get a written plan with phases and a time and cost estimate. Hire me within 14 days and the fee is deducted from your first milestone. ------------ FINISHING AN APP BUILT WITH AI TOOLS Started your mobile app with Lovable, Cursor, Bolt, Replit, Claude Code or FlutterFlow and hit a wall? I audit the code first and send you a written report: what is broken, what is missing and what it costs to fix. Then we fix it in milestones: crashes, broken data, security holes, missing backend or payments, slow screens, store rejections. ------------ THREE WAYS I CAN HELP 1. Build your product from scratch: mobile app for iOS and Android, web app, backend and admin panel, delivered in milestones. 2. Add features and AI to your existing product: AI assistants and chatbots, image and document recognition, payments and subscriptions, maps, notifications and third-party APIs. 3. Finish, fix or take over a mobile app: bugs, missing features, slow screens, store submission problems, or a developer who left. I review the code first and tell you honestly whether to fix or rebuild. ------------ MOBILE APPS I BUILD ✔ Marketplace and rental apps ✔ Booking, appointment and on-demand service apps ✔ Food, grocery and package delivery apps ✔ Ride, driver and fleet tracking apps ✔ Dating, social, health and wellness apps ✔ Rewards, loyalty, prediction and payment apps ✔ E-learning, course and quiz apps ✔ Real estate, travel, ticketing and business apps ✔ AI-powered apps: chat assistants, image recognition, document processing ✔ SaaS platforms, dashboards and customer portals ------------ SELECTED PROJECTS • FlutterGo.AI: my own product, an AI studio that turns a prompt into a working Flutter app with live preview. • Nutri AI: AI calorie tracker, photograph a meal and get calories and macros; 4.7 stars from 500+ App Store ratings. • NohAuto: towing and roadside assistance, customer and driver apps with live maps, dispatch and payments; live on the App Store. • Youth Revisited: health practitioner app with home visits, live GPS tracking, chat, Stripe payments and training modules. • Lottery Interface HD: multi-tenant lottery system; Node.js API with ticket imports, draws and PDF tickets, Next.js admin panel with reports. • CeBee Predict: football predictions and rewards app with deep linking and referrals; live on both stores. • Seek: AI object recognition app (Flutter, NestJS, OpenAI and Gemini vision). ------------ TECHNOLOGY Mobile: Flutter, React Native, FlutterFlow, iOS and Android publishing Web: React, Next.js, TypeScript Backend: Node.js, Express, NestJS, REST APIs, WebSockets Database: MongoDB, PostgreSQL, Firebase, Supabase AI: OpenAI, Claude, Gemini Payments: Stripe, Apple and Google in-app purchases ------------ READY TO START?
