Flutter Developer building clean, scalable iOS and Android apps for startups, SaaS founders, and product teams.
I've built Vibe Checkup, a mental wellness app on Flutter for Kimberly Fogg, and the backend repo for Heelpain Academy, a healthcare product for Dr. Tim Brooke. Every app I take on gets the same treatment: solid architecture, clean state management, and code that holds up in production, not just in the demo.
What I work on:
Flutter and Dart development for iOS and Android, from MVP to production scale
Firebase and Firestore integration: authentication, database rules, real time data, user profiles
API and third party integrations, including webhooks and bidirectional data sync
In app purchases and subscription flows
State management using Bloc, Riverpod, or Provider, built around clean architecture
AI powered app features and AI integrations, including working with Claude and other AI coding agents to move faster without cutting corners
Responsive UI that holds up across phones and tablets, not just one screen size
Automated testing for critical user flows, so releases don't break what already works
I also build in FlutterFlow when speed matters more than a fully custom build, and can audit or continue existing FlutterFlow projects without a rebuild.
I think in product logic before I think in screens. Before writing a line of code, I look at what the app needs to do, who's using it, and where users are likely to get stuck. That's what turns a working app into one people actually stick with.
If you need a Flutter developer who can own a mobile app end to end, from architecture through App Store and Play Store launch, send over your project and I'll come back with a specific plan.

โ ๏ธ AN APP THAT CRASHES, DELAYS LAUNCH, OR KEEPS GETTING PATCHED TOGETHER ISN'T A PRODUCT YOU CAN BUILD A BUSINESS ON.
I build high-quality iPhone and Android apps with Flutter and standalone native Android apps in Kotlin when that's the better fit for the project. If something isn't working, I dig into it until I understand why, not just what to patch.
๐ช๐๐๐ง ๐ ๐๐๐ก ๐๐๐๐ฃ ๐ช๐๐ง๐
๐น Have an idea, a spec, or a Figma file and need it turned into a real app? I build production-ready Flutter apps from scratch, structured so new features don't turn into a rewrite six months later.
๐น Want a fully native Android app instead of cross-platform? I build standalone apps in Kotlin from the ground up, when performance, platform-specific APIs, or long-term Android-only plans make that the right call over Flutter.
๐น Picked up a Flutter project from another developer and not sure what state it's actually in? I read through the codebase, flag what's fragile, and take it from wherever it currently stands to a finished, stable release.
๐น Inherited a codebase full of recurring crashes, Flutter or native Android? I trace issues through logs, state management, API calls, lifecycle handling, and native integrations instead of repeatedly patching symptoms.
๐น Building in Flutter but need a feature it can't handle well on its own, like deep native integrations or platform-specific performance work? I write native Kotlin modules to fill that gap without throwing out the rest of your Flutter codebase.
๐น Need your app talking to Firebase, a REST API, or a payment provider without silent failures? I integrate and test these connections against real edge cases, not just the happy path.
๐น Ready to ship but unsure about store requirements? I handle Google Play and App Store submissions end-to-end, then stay on to fix what real users find after launch.

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:
๐ Built FlutterFlow app systems with Firebase authentication, Firestore databases, user roles, dashboards, and backend workflows.
๐ Converted Figma designs into responsive FlutterFlow and Flutter mobile interfaces with clean UI, strong spacing, and smooth UX.
๐ Integrated real app features like APIs, push notifications, subscriptions, payments, Google Maps, booking flows, chat, admin panels, and AI-powered workflows.
๐๐ ๐๐๐๐๐๐๐:
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 โ 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 โ Structure: I map the screens, user roles, Firebase or Supabase database, authentication flow, app states, and key user actions.
Step 3 โ Build: I develop the app in Flutter, FlutterFlow, Firebase, Supabase, Dart, custom functions, custom code, or API workflows.
Step 4 โ Optimise: I test responsiveness, workflow logic, performance, database behavior, mobile usability, and broken edge cases before delivery.
Step 5 โ Launch Support: I help prepare the app for Play Store publishing, App Store submission, RevenueCat, Firebase setup, and production handoff.
๐๐๐๐ ๐ ๐๐๐๐๐:
โ Flutter App Development โ Custom iOS and Android apps with clean UI, scalable structure, backend integration, and smooth mobile performance.
โ FlutterFlow App Development โ MVPs, SaaS apps, booking apps, marketplaces, dashboards, AI apps, and business tools built fast without weak structure.
โ Firebase & Supabase Integration โ Authentication, Firestore, database rules, storage, real-time data, user profiles, and secure backend flows.
โ AI Mobile Apps โ AI chat, content generation, recommendation systems, automation flows, smart dashboards, and API-powered app features.
โ Figma to Flutter / FlutterFlow โ Mobile UI conversion with responsive layouts, modern design, clean spacing, and strong user experience.
โ API, Payments & App Features โ REST APIs, Stripe, RevenueCat, Google Maps, push notifications, chat, admin panels, and integrations.
๐ ๐๐๐๐๐๐๐๐๐ ๐๐๐๐๐ ๐๐๐๐๐๐๐๐๐
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 โ 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.

Looking for a FlutterFlow developer who builds apps that work like a real product, not just a few screens wired together?
I'm a FlutterFlow developer who helps founders, startups, and product owners turn app ideas into working iOS and Android MVPs using FlutterFlow, Firebase, Firestore, Supabase, Stripe, REST APIs, and clean mobile UX.
My focus is real user flows, solid backend logic, and the core features a product needs to actually launch and improve whether that's a fintech app, marketplace, subscription app, community app, booking app, delivery app, AI-powered app, or internal business tool.
I can help with:
FlutterFlow app development (iOS & Android MVPs)
Firebase, Firestore, and Supabase backend setup
User authentication, profiles, and onboarding
Stripe and payment gateway integration
Subscription and in-app purchase flows
API integration, push notifications, chat, and maps
Admin dashboards and tracking screens
Bug fixing, testing, and Firebase cleanup on existing apps
Most app projects fail for the same reasons: the first build is too basic, too messy, or disconnected from the actual business goal. Auth breaks. The database is poorly structured. Payment flow is unclear. Dashboards don't update correctly. The app becomes hard to improve later. That's the problem I solve.
My process: clarify the app goal and user flow, map the screens, define the backend structure, build the frontend in FlutterFlow, connect Firebase or Supabase, wire up auth and payments, test the core actions, then clean up before handoff.
If you already have a FlutterFlow app, I also fix broken Firebase connections, authentication issues, Firestore query problems, payment errors, navigation bugs, and slow or messy flows.
Send me your app idea, feature list, wireframe, or current app link, and I'll tell you exactly how I'd build or fix it.
