Is your app idea still sitting in notes, stuck in FlutterFlow, or already built but not working the way users expect? Either way, you are in the right place. Hello! I'm Emmanuel. A Mobile App Developer, FlutterFlow App Developer, UI/UX Designer, and SaaS MVP builder helping startups, founders, service businesses, and growing teams turn app ideas into clean, scalable mobile products I do not hand off pretty screens that break when real users touch them. Every app I build is structured around the real product goal: clear user flow, smooth onboarding, secure backend logic, fast performance, and a mobile experience people can trust. Here's what that looks like in practice: 🚀 Built FlutterFlow app systems with Firebase authentication, Firestore databases, user roles, dashboards, and backend workflows. 🚀 Converted Figma designs into responsive FlutterFlow and Flutter mobile interfaces with clean UI, strong spacing, and smooth UX. 🚀 Integrated real app features like APIs, push notifications, subscriptions, payments, Google Maps, booking flows, chat, admin panels, and AI-powered workflows. 𝐌𝐘 𝐏𝐑𝐎𝐂𝐄𝐒𝐒: Most developers start with screens. I start with product logic. Before I build, I review what the app must do, who will use it, what data must be saved, and where users may get confused. Then every screen, action, and backend flow has one job: guide, process, or convert. Step 1 → Audit & Strategy: I review your idea, Figma file, current app, or FlutterFlow project and identify gaps in UI, UX, backend, database, API, or launch readiness. Step 2 → Structure: I map the screens, user roles, Firebase or Supabase database, authentication flow, app states, and key user actions. Step 3 → Build: I develop the app in Flutter, FlutterFlow, Firebase, Supabase, Dart, custom functions, custom code, or API workflows. Step 4 → Optimise: I test responsiveness, workflow logic, performance, database behavior, mobile usability, and broken edge cases before delivery. Step 5 → Launch Support: I help prepare the app for Play Store publishing, App Store submission, RevenueCat, Firebase setup, and production handoff. 𝐖𝐇𝐀𝐓 𝐈 𝐁𝐔𝐈𝐋𝐃: ✅ Flutter App Development → Custom iOS and Android apps with clean UI, scalable structure, backend integration, and smooth mobile performance. ✅ FlutterFlow App Development → MVPs, SaaS apps, booking apps, marketplaces, dashboards, AI apps, and business tools built fast without weak structure. ✅ Firebase & Supabase Integration → Authentication, Firestore, database rules, storage, real-time data, user profiles, and secure backend flows. ✅ AI Mobile Apps → AI chat, content generation, recommendation systems, automation flows, smart dashboards, and API-powered app features. ✅ Figma to Flutter / FlutterFlow → Mobile UI conversion with responsive layouts, modern design, clean spacing, and strong user experience. ✅ API, Payments & App Features → REST APIs, Stripe, RevenueCat, Google Maps, push notifications, chat, admin panels, and integrations. 𝐅𝐑𝐄𝐐𝐔𝐄𝐍𝐓𝐋𝐘 𝐀𝐒𝐊𝐄𝐃 𝐐𝐔𝐄𝐒𝐓𝐈𝐎𝐍𝐒 Q: Can you build my app in FlutterFlow instead of custom Flutter? Yes. FlutterFlow is a strong choice for MVPs, SaaS apps, marketplaces, booking apps, dashboards, and AI apps that need to move fast. Q: Can you fix or continue an existing FlutterFlow project? Yes. I can audit workflows, app state, Firebase, Supabase, API calls, layout issues, and backend logic without rebuilding everything from scratch. Q: Can you work from Figma designs? Yes. I convert Figma designs into responsive FlutterFlow or Flutter screens while keeping the interface clean, modern, and user-friendly. Q: Can you add AI features or handle deployment? Yes. I can integrate AI chat, content generation, automation, APIs, payments, push notifications, and help prepare your app for App Store or Play Store launch. If you need a Flutter Developer, FlutterFlow Developer, AI App Developer, or Mobile App Developer who can build more than screens, send me your app idea, Figma design, or current project. I will come back with a specific plan, not a generic pitch. TL;DR → Flutter Developer, FlutterFlow Developer, and AI App Developer. I build clean, scalable iOS and Android apps with Firebase, Supabase, APIs, payments, push notifications, AI features, dashboards, and launch-ready user flows.

You have an app idea, maybe a Figma file, and you want it live on the App Store and Google Play without a 6-month agency timeline. That is what I build. I'm a Flutter developer with 6+ years building cross-platform mobile apps, and my recent work is almost all the same thing: turning a founder's idea or design into a working AI-powered MVP on Flutter and Firebase, shipped to both stores. 100% Job Success, Top Rated, and most of my clients come back for version 2. What I build most: AI-powered app MVPs: ChatGPT / OpenAI / Gemini chatbots, AI assistants, AI journaling and coaching, on-device ML features Flutter + Firebase apps end to end: Auth, Firestore, Cloud Functions, push notifications, real-time data MVP from a Figma file or a written spec, built clean and launch-ready FlutterFlow apps finalized: logic, RevenueCat, Firebase, store submission Payments and subscriptions: Stripe, RevenueCat, in-app purchases Verticals I've already shipped in: health and telehealth, fitness and wellness, fintech and crypto wallets, booking and service marketplaces, real estate, social and chat. My stack: Flutter, Dart, Firebase, Firestore, Node.js, REST APIs, OpenAI API, Stripe, RevenueCat, Google Maps / Mapbox, SQLite / PostgreSQL. How I work: you tell me the core idea, I map out the screens and the data model, we agree on a fixed scope for the MVP, and I build it in clear milestones so you can test as we go. Most MVPs ship in 2 to 4 weeks. If you want your AI app idea built and live on both stores, send me a message with what you have so far (idea, Figma, or an existing app) and I'll tell you exactly how I'd build it and what it costs.
