Casey S
About this gig
Have an app idea but need a Flutter developer who can turn it into a working Android and iOS app without making the project harder to manage?
I help startups, businesses and individuals with Flutter mobile app development, from new app creation to improving an existing project. Your app can be built for both platforms from one Flutter codebase, with the screens, backend connections and features your project needs.
WHAT l OFFER;
- Flutter app development
- Android app development
- iOS app development
- Backend and API integration
- UI/UX and app functionality
Before development starts, I review your app idea, required screens, user flow and features so the work follows a clear scope. Depending on your project, I can add Firebase, authentication, payments, maps, push notifications, admin features and third party APIs.
You will receive the agreed app features, organized source code and support with testing and store submission when included in the project.
Send me your app idea, number of screens, required features, design or reference, and whether you need Android, iOS or both. I will review the requirements with you before we begin.

I am a full stack developer building web and mobile apps for startups and business owners. I work mainly in React, Flutter, and Python, taking projects from a rough idea through to something people can actually use. Clients usually come to me needing an MVP built fast or an existing app fixed and stabilized. I write code I am willing to hand off to another developer later, and I tell clients early if a timeline or scope isn't realistic. Past work onboarding flows, payment integration, cleaning up slow database queries.
