About this gig
Need a mobile app that actually ships? I build production-ready iOS and Android apps with Flutter,from MVP to store launch.
Most app projects fail on scope, not code.Before I write a line,we agree on screens, features and a delivery date, so you know exactly what you are getting.
WHAT I BUILD
- Startup MVP apps to validate your idea fast
- SaaS and subscription apps with user accounts
- Booking,delivery,e-commerce and marketplace apps
- Fitness,education,social and on-demand apps
- Admin dashboards, Play Store and App Store publishing
MY STACK
Flutter | FlutterFlow | Dart | Firebase | Supabase | REST APIs | Stripe | Push notifications
WHAT YOU GET
- One codebase, both iOS and Android
- Clean, commented source code, yours to keep
- Pixel-accurate UI, responsive on every screen
- A working backend: auth, database, storage, payments
- A signed build, ready for the stores
WHY ME
I am a full-stack mobile app developer, not a template reseller. You get direct communication, progress updates you can follow, and an app another dev could pick up without a rewrite.
Not sure which package fits? Send me your idea and I will reply with a free scope and a fixed quote.
Let's build.

FAQ
Can you build both iOS and Android apps?
Yes. I build with Flutter/flutterflow, so one codebase runs natively on both iOS and Android. You get the same features, the same design and the same performance on each platform, without paying twice for two separate builds.
Do I get the source code?
Yes, on every package. You receive the full, commented Flutter project files. The app is yours: you can host it, extend it, or hand it to another developer at any point. I never lock clients into needing me.
Can you publish my app to the App Store and Google Play?
Yes, store publishing is included in the Premium package and available as an extra on the others. You will need your own Apple Developer and Google Play developer accounts. I handle the builds, store listing setup and compliance review.
Do you build the backend too, with login and database?
Yes. I set up Firebase or Supabase or django for authentication, database, cloud storage and push notifications, and I can connect any REST API you already have. Payments via Stripe, Paystack or Flutterwave are supported.
How much does a full mobile app cost?
It depends on screen count and features. A simple MVP starts around the Standard package. Apps with payments, chat, maps or an admin panel land at Premium or above. Send me your feature list and I will give you a fixed quote, free.
I only have an idea and no designs. Can you still help?
Absolutely. Many clients start with just an idea. I will turn it into a screen-by-screen plan, design the UI, and build it. If you do have Figma or Adobe XD files, I will match them precisely.
Can you fix or finish an app another developer started?
Yes. Send me the repository or project files and I will audit them first, then quote for the fix or the remaining work. I do this often. Please message me before ordering so I can scope it properly.
How long does an MVP app take to build?
A focused MVP typically takes two to three weeks. Larger builds with payments, real-time features or an admin dashboard run three to five weeks. I give you a firm delivery date before you order, not an estimate.
Do you offer support after delivery?
Yes. Every package includes bug fixes after handover, and Premium includes 30 days of support. After that I offer monthly maintenance for updates, new features and OS compatibility.
Can you build a SaaS or subscription app?
Yes. Subscription apps are a core part of what I do: tiered plans, in-app purchases, recurring billing, user roles and a web admin dashboard to manage it all. Tell me your pricing model and I will build to it.
