About this gig

Need an app on iPhone and Android from one codebase? I build Flutter apps that are fast, clean and ready for the stores.


I built LifeThreads and Mezzo, my own Flutter apps, end to end: design, code, backend and store submission.


What you get:

  • Clean Flutter code (Riverpod, go_router), easy to extend
  • Modern design in your brand colours, light or dark
  • Login, local database, push notifications, in-app subscriptions on request
  • Backend or API integration (Firebase, REST, or a custom backend)
  • English, German and Arabic (right to left) on request
  • Tested on simulators and real devices; the source code is yours

Please message me before ordering with a short description of your app, so I can confirm the scope and timeline.

I build mobile apps, backends and websites, end to end. I'm George, founder of GK Coding in Linz, Austria. I trained as a software developer (Lehrabschluss Softwareentwicklung) and have been programming since 2019. My own products: LifeThreads (a Flutter memory app, now in App Store review), Mezzo and Wandvue (a SaaS for interior designers with a FastAPI backend, web and mobile apps). I work in Flutter, native iOS and Android, FastAPI and Node with Postgres, and React. I also publish apps and fix store rejections. Tested builds, clear updates, honest timelines.
