I will develop your cross platform android ios app with kmp and backend


Level 2
About this gig
Need one developer who can build your app from start to finish, not just the screens, but the backend and database behind it too?
I'm Hazrat. I've completed 200+ projects on Fiverr with a 5.0 rating. I build apps that run on both Android and iPhone from a single codebase using Kotlin Multiplatform, so you're not paying for two separate builds; you get one that runs natively on both platforms.
I also build what's behind the app: your APIs, database, and server setup. I use Kotlin Spring Boot for the backend, PostgreSQL or MongoDB for the database, and Docker so your app can actually go live, not just run as a demo.
I work with founders building their first app, and business owners replacing something old with something that actually works. I'll tell you honestly what your project needs, how long it'll take, and what it'll cost before you spend a dollar.
What's included:
- One app, working on Android and iPhone
- A working backend with a real database
- Docker setup, ready to launch
- Direct work with me, no outsourcing
Message me before you order; two minutes of chatting saves both of us.
