Hi, I'm Jemin Padsala 👋 Have an app idea but need someone who can turn it into a working product? Or maybe you already have a Flutter app that needs new features, better performance, or difficult bugs fixed. That's where I can help. I'm a Flutter Developer with 5+ years of experience building and improving mobile applications for startups, businesses, and founders. I build Android, iOS, Web, and Desktop applications using Flutter and Dart, with a focus on clean code, smooth user experiences, reliable functionality, and easy maintenance. I can work with you from idea to launch or join your existing project and continue development from where your current team left off. What I Can Do For Your Project ➤ Build Flutter apps from scratch ➤ Convert Figma designs into Flutter ➤ Develop MVPs for startups ➤ Build Android & iOS applications ➤ Develop Flutter Web applications ➤ Continue development on existing Flutter apps ➤ Fix Flutter bugs and crashes ➤ Add new features ➤ Improve app performance ➤ Refactor existing code ➤ Connect REST APIs and GraphQL ➤ Integrate Firebase and Supabase ➤ Add AI features with OpenAI and Gemini ➤ Build AI chatbots and assistants ➤ Integrate Stripe, Razorpay, PayPal, and subscriptions ➤ Add Google Maps and location features ➤ Implement push notifications ➤ Build real-time features ➤ Prepare apps for App Store and Google Play Flutter Development I use Flutter and Dart to build applications that work smoothly across platforms while keeping the code organized and easy to maintain. Flutter • Dart • FlutterFlow • Android • iOS • Flutter Web Architecture & State Management For every project, I choose an approach that fits the application's actual needs. Clean Architecture • MVVM • BLoC • Cubit • Riverpod • Provider • GetX The goal is to keep the application structured without making the development unnecessarily complicated. Backend & API Integration I can connect your Flutter application with the services it needs: Firebase • Supabase • REST APIs • GraphQL • WebSockets • Authentication • Database Integration • Push Notifications AI Features Want to add AI to your mobile application? I can integrate features such as: ➤ OpenAI API ➤ ChatGPT-based Features ➤ Google Gemini ➤ AI Chatbots ➤ AI Assistants ➤ AI-Powered Search ➤ Content Generation ➤ Speech-to-Text ➤ Text-to-Speech I focus on using AI where it can provide real value to your application and users.

FlutterFlow Certified Expert and Flutter developer - 70+ apps live, 10,000+ hours logged, and 100% Job Success across 69 contracts. I build AI-powered mobile apps and MVPs on Firebase and Supabase, and I get them through App Store review. Most app ideas die between prototype and production. AI tools generate demos in an afternoon. Demos don't survive real users, real payments, or Apple's review team - and that gap is where most projects quietly fail. That's the part I do. WHAT I BUILD - AI-powered apps - ChatGPT and Gemini integration, voice, image recognition, automation - MVPs - validated and launched in weeks, built so they don't need a rewrite later - Production apps - scalable, App Store and Play Store ready, iOS and Android - Rescue work - broken apps, stalled projects, developers who disappeared - Long-term partnerships - I don't hand off and vanish TECHNICAL DEPTH - FlutterFlow and Flutter (Dart), custom code and native integrations - Backend architecture: Firebase, Supabase, Cloud Functions, REST APIs - Payments: Stripe, Razorpay, in-app purchases and subscriptions - Real-time: chat, GPS tracking, live dashboards, push notifications - App Store compliance across 70+ published apps, including regulated categories WHY CLIENTS STAY - 100% Job Success across 69 projects - zero failed deliveries in six years - One client kept me on for 4,400+ hours over four years - FlutterFlow Certified Expert, and Most Active FlutterFlow Community Member (2023 and 2025) - I tell you when your scope is wrong, when a feature isn't worth building, and when I'm not the right fit Industries: FinTech, HealthTech, EdTech, eCommerce, SaaS, on-demand delivery, EV charging, marketplaces. Anyone can generate code now. What you're actually hiring is judgment about what to build, and someone who owns the outcome when a payment bug hits production on a Friday night. HOW TO START Send me your project details, goals, or the problem you're stuck on. I'll come back with honest feedback on the best path forward - including whether you need me at all. If I'm not the right fit, I'll say so and point you somewhere better.

Your Flutter app should be live, performing, and making money — not stuck in development or failing App Store review. I've shipped apps to 100K+ active users across 1M+ monthly sessions, most recently on a live sports platform where real-time reliability was non-negotiable. With 5+ years building production-grade Flutter apps for iOS and Android, I take apps end-to-end: turning complex Figma designs into pixel-perfect UIs, integrating REST APIs and real-time features that scale, and building subscription systems that convert and retain. What I deliver: ✦ Launch-ready Flutter UI — From your Figma file to a pixel-perfect, responsive Flutter app on iOS and Android. E-commerce, job portals, trip planners, sports dashboards — built to handle real users from day one, not just the demo. ✦ Integrations that hold under load — REST APIs, GraphQL, real-time feeds, payment gateways, Google Maps, push notifications, and complex third-party SDKs — connected cleanly and stress-tested, not hacked together for the deadline. ✦ Subscriptions that convert and retain — End-to-end RevenueCat setup on iOS and Android: paywalls, entitlements, pricing configs, and every edge case between the first purchase and auto-renewal. ✦ A backend your app won't outgrow — Firebase Auth, Firestore, Cloud Functions, and real-time sync — architected to scale with your growth from launch to 100K users without a rebuild. ✦ Live on both stores, without the rejection loop — Full App Store and Play Store submission handling: build signing, guideline compliance, rejection fixes — shipped on schedule.

Larger products with complex integrations run 6–10 weeks — with working builds you can test throughout, not just at the end. I write Flutter code your next developer will genuinely thank you for: clean architecture, clear communication, zero shortcuts. Got something you're building?
