Absolutely. Every Android app is delivered as a signed APK and AAB file meeting all Play Store guidelines. Premium package includes full Play Store submission. I handle app signing, manifest setup, and store listing configuration on your behalf.
Can you integrate Firebase, REST APIs and payment gateways?
Yes — I integrate Firebase authentication, real-time database, push notifications, REST APIs, Google Maps, payment gateways, and social logins into every Android application. I also build Node.js or NestJS backends if you need a complete full-stack mobile solution.

A simple MVP Android app takes 5 days. A full-featured business app with APIs, Firebase and payments takes 10 days. Complex e-commerce or on-demand Android platforms take 18 days. Message me with your requirements and I will give you an exact timeline and quote.
