Whether you're launching an MVP, scaling an existing product, fixing a struggling codebase, or building a production-ready mobile application from scratch, I help businesses turn ideas into reliable, high-performance apps. I'm Gbenga, a Flutter Developer and Native Android Developer (Kotlin & Jetpack Compose) with 4+ years of experience building cross-platform and Android applications for startups, businesses, and growing products. I've contributed to applications across FinTech, Hospitality, Education, Real Estate, Cryptocurrency, Mobility, Business Management, and AI-powered products building features users rely on every day. I don't believe in using the same technology for every project. Flutter is often the best choice when you need a high-quality iOS and Android application with a single codebase, faster development, and lower maintenance costs. Native Android with Kotlin & Jetpack Compose is the better option when your product requires platform-specific features, maximum performance, or a long-term Android-first strategy. ๐–๐‡๐€๐“ ๐ˆ ๐‚๐€๐ ๐‡๐„๐‹๐ ๐˜๐Ž๐” ๐๐”๐ˆ๐‹๐ƒ โœ” Cross-Platform Mobile Applications (Flutter) โœ” Native Android Applications (Kotlin & Jetpack Compose) โœ” AI-Powered Mobile Applications โœ” Startup MVP Development โœ” Firebase & Appwrite Backend Integration โœ” REST API & GraphQL Integration โœ” Authentication (Google, Apple, Email, Phone) โœ” Payment Gateway Integration โœ” Push Notifications (FCM) โœ” Google Maps & Location Services โœ” Real-Time Applications & Live Synchronization โœ” Chat & Messaging Applications โœ” Offline-First Mobile Applications โœ” Bug Fixing & Performance Optimization โœ” Code Refactoring & Feature Development โœ” Firebase Cloud Firestore โœ” App Architecture & Clean Code โœ” Google Play Store & Apple App Store Deployment โœ” Long-Term Application Maintenance ๐๐‘๐Ž๐‰๐„๐‚๐“๐’ ๐ˆ'๐•๐„ ๐‚๐Ž๐๐“๐‘๐ˆ๐๐”๐“๐„๐ƒ ๐“๐Ž โ€ข MyPal โ€” Hospitality & Lifestyle platform.

Hi, I'm Wale, a Mobile App Development Expert. I build cross-platform mobile apps using FlutterFlow, Flutter, and React native, 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 that are ready to build applications that users would actually use. 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 ๐Ÿš€ 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. ๐Ÿš€ 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. ๐Ÿš€ Real-Device Testing โ€” Every app is tested on actual iOS and Android hardware before delivery. Not simulators. Not assumptions. ๐Ÿš€ 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. TOOLS & SERVICES ๐Ÿš€ Platforms & Frameworks - FlutterFlow ยท Flutter ยท React.js ยท Firebase Firestore ยท Supabase ยท Firebase Authentication ยท Firebase Cloud Functions ยท Google Cloud ยท Hygraph CMS ๐Ÿš€ Integrations - OpenAI API ยท Claude API ยท Google Gemini ยท Google Vision ยท Google Cloud TTS ยท ElevenLabs ยท RevenueCat ยท Stripe ยท Paystack ยท REST APIs ๐Ÿš€ Delivery - iOS TestFlight ยท App Store Submission ยท Google Play Console ยท Google Play Internal Testing ๐Ÿš€Services - Cross-Platform Mobile App Development ยท MVP Development ยท AI-Powered App Development ยท SaaS Mobile Applications ยท Subscription & Payment Integration ยท Firebase Backend Architecture ยท Supabase Backend Setup ยท FlutterFlow Bug Fixes & Project Rescue ยท App Performance Optimization 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. 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, you own every source code, 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.
