I will develop a native android app with kotlin and database backend
Wismitha Peiris
About this gig
Want a polished Android app that's actually shipped to the Play Store by someone who's already done it?
I independently designed, built, and published a full SaaS app live on Google Play (eventplanners.app) Kotlin, Jetpack Compose, Firebase backend, Google Play Billing, the works. I can do the same for you.
What I build:
- Native Android apps in Kotlin + Jetpack Compose + Material 3
- Firebase backend: Auth, Firestore, Storage, Cloud Functions, push (FCM)
- In-app purchases & subscriptions (Google Play Billing)
- AI features (GPT text generation, smart suggestions) if you want them
- Full Play Store deployment and release setup
Why me: Most app sellers have never shipped a real, paid, published product. I have and I built every layer of it myself. You get a clean, modern, maintainable app, not a clunky prototype.

FAQ
I'm not sure which package I need — can you help?
Absolutely. Message me before ordering with a short description of what you want to build, what you'll connect it to, and your rough budget, and I'll recommend the right package or send you a custom quote. Most real projects work best as a custom offer tailored to your exact needs.
Do you provide the source code?
Yes. You receive full, clean, documented source code on every package so you fully own and can build on your system. If you'd also like a written setup/usage guide, add the "Source code + documentation" extra.
Will you publish my app to the Google Play Store?
Yes — full Play Store publishing is included in the Premium package, and I've published apps to Google Play myself. You'll need your own Google Play Developer account (a one-time $25 Google fee); I'll guide you through it and handle the upload, store listing, and release.
Do you provide the UI/UX design, or do I need to send designs?
Both options work. If you have designs or wireframes (for example in Figma), I'll build to them exactly. If you don't, I can design a clean, modern interface for you using Material 3 — just describe your idea and any apps whose look you like.
Can you add a backend — user accounts, a database, or push notifications?
Yes. The Premium packages include a Firebase backend with user authentication, a cloud database, file storage, and push notifications. Tell me what your app needs to store and I'll set it all up.
Can you add payments, subscriptions, or in-app purchases?
Yes — I've implemented Google Play Billing for a live subscription app. In-app purchases and subscriptions are included in the Premium package; share your pricing model and I'll build it in.
Can you add AI features to my app?
Yes — I specialize in AI integration and can add features like chatbots, smart suggestions, or text generation (GPT/Gemini) to your app. Let me know what you have in mind and I'll scope it for you.
What do you need from me to get started?
A clear description of your app and its main features, any existing designs or branding (logo, colours), example apps you like, and your deadline. For backend or publishing work I'll also need the relevant accounts/access. The more detail you share up front, the faster I deliver.
