I will be your android app developer with kotlin java and jetpack compose kotlin expert


About this gig
I build professional, high-performance Android apps using Kotlin and Java clean architecture, real production code, not patched-together tutorials. Whether you're building a new app from scratch, fixing a broken one, or upgrading an old Java codebase to modern Kotlin with Jetpack Compose, I deliver working software on time.
What I build:
- Business and enterprise Android apps
- E-commerce and marketplace apps
- Booking, delivery, and service apps
- Social and community apps
- AI-powered apps (chat, content generation, smart features)
- Utility and productivity apps
Tech I work with:
- Kotlin (primary language, modern best practices)
- Java (legacy support, full codebase migrations)
- Jetpack Compose (modern declarative UI)
- MVVM + Clean Architecture
- Firebase (Auth, Firestore, Realtime Database, Push Notifications)
- REST APIs and third-party SDK integrations
- Android Studio (full project delivery, Play Store ready)
- Room, Retrofit, Hilt/Dagger, Coroutines, Flow
Why work with me:
- I write production-grade code with proper architecture (MVVM, clean separation of concerns) not quick fixes that break at scale.
- Your project is fully yours: clean, documented code with no hidden dependencies

FAQ
Do you write in Kotlin or Java?
Both — Kotlin is my primary language and the current Android standard. I also work with Java for legacy codebases or Java-specific project requirements.
Can you migrate my old Java app to Kotlin?
Yes, this is a common request. Message me with details and I'll quote a migration plan based on your codebase size.
Do you use Jetpack Compose or XML for UI?
I use Jetpack Compose for new projects (it's the modern standard) and XML where the project already has an existing UI structure or Compose isn't appropriate.
Can you fix bugs in my existing Android app?
Yes — send me the details (error logs, crash reports, what's broken) before ordering and I'll quote the fix accurately.
Will you help me publish to the Play Store?
Yes, Play Store upload is included in Premium and available as an add-on on Standard. You'll need an active developer account ($25 one-time Google fee if you don't have one)
