I will develop android app with firebase in kotlin
Nikhil Khairnar
About this gig
Building an Android app that actually works in the real world takes more
than code that compiles it needs solid architecture, reliable data sync,
and a clean user experience from day one.
I'm a Kotlin Android developer with production experience building
real-time, Firebase-backed apps using MVVM architecture.
What I bring:
Clean MVVM architecture with Coroutines, Flow, and Hilt
Firebase integration Authentication, Realtime Database, FCM
REST API integration using Retrofit and OkHttp
Offline-first data handling with Room DB zero data loss on reconnect
Material Design UI with Jetpack Compose
Recent work includes CaptionAI (AI content app) and CoffeeGo (ordering app,
200+ concurrent users in testing), plus internship experience building a
metro booking app that cut booking steps by 30% and improved API response
time by 35%.
I write clean, well-structured code that's easy to maintain after delivery
not something that just works once.

FAQ
Which package should I choose?
Basic is best if you just need a working core app with source code, no design work. Standard adds app design, icon, and splash screen the right fit for most buyers. Premium includes backend development and Play Store submission help pick this if you want a complete, launch-ready app.
Do you provide the source code?
Yes, full source code is included in every package, along with basic comments so you or another developer can maintain it later.
Can you work with my existing app instead of building from scratch?
Yes. Share your repo or relevant files and I'll review the codebase before quoting scope and timeline I don't start work until I'm confident I can deliver what you need.
What information do you need from me to get started?
A brief description of your app's core features, any design references or wireframes you have, and whether you already have a Firebase project set up. If not, I can set one up for you.
Do you sign an NDA before starting?
Yes, I'm happy to sign one before reviewing any code or business details.
What happens if I need more revisions than my package includes?
You can add extra revisions individually, or I'm happy to discuss upgrading your package if the scope has grown.
Do you offer ongoing support after delivery?
Premium package includes 7 days of post-delivery support. For Basic and Standard, ongoing support can be arranged separately if needed.
