I'd rather show you what I can do than tell you. Imagine this: you wake up Monday, your app is on the App Store, the design is pixel-perfect, your Firebase bill is a fraction of what your last developer warned you about, and your users are already messaging you about the AI features. That's not a pitch that's a Tuesday for the founders I work with. Send me your Figma file. I'll send you back a personalised Loom video showing exactly how I'd architect your app, where I'd save you money on Firebase, and how I'd add AI features your competitors haven't thought of. That's my promise and it costs you nothing to find out. I'm Joseph a Senior FlutterFlow Developer who turns Figma designs into production-ready iOS and Android apps with optimized Firebase backends and built-in AI. No agency markup. No 3-month timelines. WHAT FOUNDERS GET WHEN THEY HIRE ME: 🔹 Dakota Fintech MVP shipped in 24 days. 20-screen Figma design straight to live App Store launch. Zero scope creep. Hit his Series A demo deadline with a week to spare. 🔹 Tobias Firebase bill cut by 70%. Restructured his Firestore architecture and watched his monthly bill drop from "panic" to "rounding error." 🔹 Gabriel Broken build rescued in 3 weeks. Took over a half-finished FlutterFlow project his last developer abandoned and shipped to production. 🔹 AI-powered SaaS Built ChatGPT + Claude into a FlutterFlow app with custom prompts and streaming responses. Replaced a 4-person support team with an AI agent handling 70%+ of tickets. WHERE I SHINE: 🔹 AI mobile apps (chatbots, AI agents, voice AI, personalisation) 🔹 Fintech (payments, subscriptions, ledger logic that balances) 🔹 Health & fitness (tracking, wearables, custom calculations) 🔹 SaaS MVPs & B2B mobile apps 🔹 Two-sided marketplaces (booking, payments, ratings) 🔹 FlutterFlow rescue work when someone else broke it, I fix it MY TECH: Mobile: FlutterFlow • Flutter • Dart • Figma Backend: Firebase (Firestore, Auth, Cloud Functions) • Supabase • Stripe • RevenueCat • REST APIs AI: ChatGPT • Claude • Gemini • Whisper • DALL-E • ElevenLabs • Pinecone • RAG • FlutterFlow AI Agent Builder Launch: App Store • Google Play • TestFlight • Push Notifications • In-App Purchases FREQUENTLY ASKED QUESTIONS: ❓ How long does a FlutterFlow MVP take? Most Figma-to-App-Store builds ship in 24–35 days. Complexity of your custom logic and integrations sets the exact number. ❓ Can FlutterFlow really build production-ready apps? Yes with custom Flutter code where it matters. Dakota's fintech app runs live on both stores. I don't ship "prototypes with limits." ❓ Will my Firebase bill actually stay low? Yes, if it's structured right from day one. Most bill spikes come from bad Firestore modeling nested subcollections, unbatched reads, missing indexes. I fix those before you ever see them. ❓ Can you integrate Stripe subscriptions and one-time payments? Yes Stripe Checkout, Payment Element, Subscriptions, Connect, and webhook-driven event handling. Plus RevenueCat for in-app purchases on iOS/Android. ❓ Can you integrate custom REST APIs and third-party SDKs? Yes. Authentication, pagination, retry logic, webhook signing, and error handling I write custom Flutter code when FlutterFlow's built-in API blocks aren't enough. ❓ Can you add ChatGPT, Claude, or Gemini to my app? Yes including streaming responses, prompt engineering, RAG pipelines, and the FlutterFlow AI Agent Builder. I can also integrate voice AI (ElevenLabs, Whisper) and image generation (DALL-E). ❓ Do you handle App Store and Google Play submission? End-to-end TestFlight, store listings, screenshots guidance, review responses, and rejection appeals if they happen. ❓ Will I own the FlutterFlow project and code? 100%. The project lives in your FlutterFlow account. You own everything design, logic, and full code export rights. Never locked in. ❓ What if my current FlutterFlow project is already broken? Rescue work is 30% of what I do. Send me the project and I'll audit it free most builds can be salvaged faster than starting over. ❓ How do we start? Send me a message with your Figma file, current project, or idea. I'll come back within 60 minutes with a specific plan not a sales pitch. HOW IT FEELS TO WORK WITH ME: Loom walkthroughs at every milestone. Documentation and handoff playbook so you're never held hostage. Honest architecture pushback instead of quiet shortcuts. 60-minute response time during work hours. YOUR FREE 30-MINUTE ARCHITECTURE REVIEW: Send me your Figma file, existing FlutterFlow project, or your idea. Zero obligation. If we're a fit, we move fast. 🔧 EXPERTISE: FlutterFlow | Flutter | Dart | Figma to FlutterFlow | Firebase | Firestore | Stripe | RevenueCat | Supabase | REST API | iOS | Android | AI Integration | ChatGPT | Claude API | OpenAI API | Gemini

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 Flutter Developer, FlutterFlow Developer, AI App Developer, and Mobile UI UX Designer building clean, scalable mobile apps for startups, SaaS founders, coaches, marketplaces, service businesses, and teams. 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.
