I will build mobile app for you
Trafford P.
About this gig
I build fast, scalable mobile and web apps that feel polished and hold up with real users, not just in a demo.
With 8+ years of experience, I develop cross-platform apps for iOS and Android using React Native and Flutter, alongside modern web apps in React and Next.js. The apps I've worked on have been downloaded over 3.5 million times between them, including Zigazoo, a consumer social app past 1.5M downloads, and Kinnu, a polished, gamified learning app, both live on the App Store and Google Play.
What I do:
- Cross-platform mobile apps (React Native, Flutter) for iOS and Android
- Full-stack web apps (React, Next.js, Node)
- Backend and integrations: Supabase, Firebase, REST APIs, Stripe, auth
- AI-powered features: LLM chatbots and assistants, recommendation systems, voice and image capabilities
- App Store and Google Play submission
- Clean, maintainable, well-tested code
Every project is different, so please message me before ordering. I'll confirm the scope and give you an accurate quote and timeline. I'm responsive, work full-time hours, and I'd genu

FAQ
Which should I choose, React Native or Flutter?
Both give you one codebase across iOS and Android, which keeps cost and maintenance down. React Native suits most consumer and content-driven apps; Flutter is great for highly custom, animation-heavy interfaces. Message me your idea and I'll recommend the right fit honestly.
Do you provide the source code?
Yes. You own all the code, fully, at delivery. It's clean, documented and maintainable, so you or another developer can build on it later with no lock-in.
Do I need my own backend, or can you build that too?
I can do both. If you have a backend or API, I'll integrate with it. If not, I'll build one using Supabase or Firebase, with auth, database, notifications and payments as needed. Let me know what you have and I'll scope it.
Can you add AI features like a chatbot or recommendations?
Yes, this is a core focus of mine. I integrate LLM chatbots and assistants, recommendation systems, and voice or image features using APIs like OpenAI, built properly into your app rather than bolted on.
Can you submit the app to the App Store and Google Play?
Yes, I handle the full submission to both stores, including the setup and compliance steps that often trip people up. It's included in the Premium package and available as an extra on the others.
How do we start?
Message me before ordering with a short description of your app. I'll confirm the scope, recommend the right package, and give you a realistic quote and timeline before you commit, so there are no surprises.
