What You'll Receive
Full Description
Need a mobile app for Android and iOS? I build cross-platform apps with Flutter and React Native — one codebase, both platforms, production-ready.
Whether you need a simple MVP, a customer-facing app for your business, or a full product with backend and admin dashboard, I handle the entire mobile stack: UI, state management, API integration, local storage, build pipeline, and app store publishing.
What I can build:
• Consumer apps — e-commerce, marketplace, delivery, booking
• Business apps — internal tools, field teams, customer portals
• SaaS mobile clients — paired with your existing web app
• Utility apps — scanners, calculators, reference tools
• Educational apps — courses, quizzes, progress tracking
• Multi-role apps — admin, staff, customer roles in one app
Full stack I work with:
Flutter · Dart · React Native · Expo · Firebase (Auth, Firestore, Storage, Cloud Messaging) · Node.js · Express · MongoDB · PostgreSQL · REST APIs · Stripe · Paystack · Flutterwave · Google Maps · CodeMagic CI/CD · Fastlane
What every app includes:
• Custom UI built to your spec (not a template)
• Android + iOS from one codebase
• Firebase or custom backend authentication
• Push notifications
• Local storage / offline support
• API integration with your backend
• Custom splash screen and app icon
• Automated builds via CodeMagic CI/CD
• APK + IPA deliverables
• Post-launch Play Store / App Store submission guide
• Full source code + documentation
• 30–60 day post-launch support (per package)
How I work:
1. You describe the app — features, users, and goals
2. I confirm scope, timeline, and price
3. I build a working version and share an APK for you to install on your phone
4. You review, request changes, and I refine
5. Final delivery — APK, IPA, source code, and deployment guide
Why clients choose me:
I've built cross-platform mobile apps for schools, SaaS platforms, and marketplaces. My recent school management app was built with Flutter + CodeMagic CI/CD and is deployed to both Android and iOS. Every app ships with a real APK you can install and test before final payment — no guessing whether it works.
Send me your app idea and I'll tell you exactly what's possible, what it costs, and how long it takes.

Frequently Asked Questions
Every package includes 7–30 days of post-launch support. After that, a monthly maintenance retainer covers bug fixes, OS updates, minor feature additions, and priority support.
You own everything — 100%. Full source code, build pipeline, and both store accounts stay under your name. No platform lock-in, no recurring fees to me.
Yes, before work starts. Once I begin and share a testable APK, refunds aren't available — but you only pay final after installing and testing the working app.
Basic: 10 days. Standard: 15 days. Premium: 21 days. Rush delivery available — message me before ordering.
Basic apps support offline login and cached content. Standard and Premium include full offline sync — user data saved locally and synced when back online. Best for field apps, delivery apps, and any app used in low-connectivity areas.
Yes. Premium tier includes RevenueCat integration (handles iOS + Android in-app purchases and subscriptions cleanly). For one-time purchases or web-based payment, Stripe, Paystack, or Flutterwave work too.
Firebase is fastest for most apps — real-time database, authentication, storage, push notifications, all managed by Google. For complex apps with custom logic, I build Node.js + Express + MongoDB/PostgreSQL backends.
Yes. Standard and Premium include CodeMagic CI/CD for automated builds and step-by-step publishing guidance. I can also publish directly to your accounts for an add-on fee.
Every delivery includes a working APK you install directly on your Android phone — no Play Store needed. For iOS, I share an IPA or TestFlight link. You test the real app before final payment.
Yes. Flutter and React Native deliver both platforms from a single codebase — so you don't pay twice. Native Android (Kotlin) or native iOS (Swift) builds are available separately if you need platform-specific performance.
