Hi, I'm Wale, a Flutterflow Expert. I build cross-platform mobile apps using FlutterFlow with Firebase, Supabase or custom backends. I deliver clean, fast, and launch-ready MVPs, AI-powered apps, SaaS products, subscription platforms, and full-scale applications that run natively on iOS and Android platforms.
I work directly with startup founders, non-technical entrepreneurs, and product teams ready to stop planning and start shipping. I've built and delivered apps across food delivery, music streaming, multiplayer gaming, sports, social platforms, AI tooling, and SaaS products; handling everything from UI through backend architecture to App Store and Google Play submission.
MY DEVELOPMENT METHODOLOGY
๐ Scope Before Build โ Every engagement starts with a precise scope agreement. Before anything is built, I sit with you and use my experience across dozens of shipped apps to help you see your own idea more clearly. By the time we finish this conversation, you will understand your own project better than you did when we started, and we will both know exactly what is being built.
๐ Core-First Delivery โ I build the feature that proves your concept works before anything else. The version that validates your idea ships first. Everything else builds on top of a working foundation.
๐ Real-Device Testing โ Every app is tested on actual iOS and Android hardware before delivery. Not simulators. Not assumptions.
๐ Clean Handover โ You receive a fully organized FlutterFlow project, backend access, and documentation, all connected to your accounts. Complete ownership with nothing held back.

FREQUENTLY ASKED QUESTIONS
Q: Have you actually deployed apps to the Apple App Store and Google Play Store?
Yes. I have taken apps through the full submission pipeline on both platforms. From provisioning profiles, bundle IDs, and App Store Connect configuration on the iOS side, to Google Play Console setup, signed APK generation, and internal testing tracks on Android. Deployment is not an afterthought in my process. I account for store requirements during development so that submission is not a scramble at the end.
Q: How long does a FlutterFlow mobile app project typically take from start to delivery?
A focused MVP with 4 to 6 screens, authentication, and a live Firebase or Supabase backend typically takes 1 to 2 weeks. Apps with AI integrations, payment flows, real-time multiplayer, or complex backend logic take 3 to 6 weeks depending on scope. I give you a precise timeline during our scoping conversation.
Q: Will I fully own the app and backend after the project is complete?
Yes. The FlutterFlow project, Firebase or Supabase backend, all API connections, and every asset delivered are linked to your accounts, not mine. You own everything completely from day one. I do not retain access, hold dependencies, or lock you into any ongoing arrangement unless you specifically want one.
Q: Can you integrate AI features like ChatGPT, Claude, or Gemini into a FlutterFlow app?
Yes. AI integration is one of the fastest-growing areas of my work. I connect FlutterFlow apps to OpenAI, Anthropic Claude, Google Gemini, Google Vision for OCR, Google Cloud TTS for voice output, and ElevenLabs for voice cloning. Chatbots, document processing, speech-to-text, AI-generated content, and intelligent recommendation systems are all within scope.
Q: I have an existing FlutterFlow project that is broken or incomplete, can you fix it?
Project rescues are a regular and significant part of my work. Send me access to the FlutterFlow project and describe what is broken, missing, or stuck. I will review the codebase, diagnose the root cause, and give you an honest written assessment of what it will take to complete or repair it before any commitment is made.

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:
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.

Your app should be an asset, not a technical headache.
I specialize in high-velocity development for founders new start up businesses who need to launch, validate, and scale without the overhead of a full agency.
Most mobile projects fail because of "Feature Creep" and "Design Friction." I solve both.
By utilizing a Figma-First development workflow, I cut development cycles by 45% and eliminate the common "it doesn't look like the design" bug entirely.
Specialized Service Tiers:
- The 4-Week MVP: Complete build-out of core features, Firebase setup, and Store submission.
- The UI/UX Audit & Port: Converting your existing "broken" prototype into a high-performance FlutterFlow engine.
- The Scalability Sprint: Implementing custom API integrations, Cloud Functions, and advanced State Management for established apps.
The "Founder-Ready" Metric:
- Cost Efficiency: Save 40% on initial build costs compared to traditional Swift/Kotlin development.
- Deployment Speed: Average turnaround of 28 days from Figma file to functional Beta.
- Scale Ready: 100% Firebase integration designed to handle the first 10,000 users without infrastructure changes.
The 2026 The Modern Tech Stack Powering Your Product:
- Interface: Figma (Systematized Components & Prototyping)
- Engine: FlutterFlow (Clean Logic & Custom Widgets)
- Data: Firebase (Auth, Firestore, Messaging) + Supabase
- Payments: Stripe & RevenueCat Integration
Vertical Expertise:
SaaS ยท Fintech ยท Health & Fitness (Workout/Gym) ยท Marketplaces
Stop waiting for "next month."
Every week spent in development is a week of lost user data and revenue.
