Android Social Media App Development -- 2

I need an experienced developer to build a full-featured social media application for Android. The core experience should let users register, create a profile, post text / images, follow or connect with others, like and comment, and receive real-time notifications. A clean, modern interface that feels familiar to everyday social platforms is essential.

I’m open to Java or Kotlin, but the code must be well-documented and structured for future scaling. Firebase (or another reliable BaaS) can be used for authentication, real-time database, and push notifications as long as it keeps the app lightweight and responsive.

Deliverables
• Production-ready APK for testing on recent Android versions
• Complete source code with clear README covering build steps and dependencies
• Brief hand-off document outlining architecture, third-party libraries, and how to add new features

Acceptance criteria
• Smooth sign-up / login flow, including social login option
• Feed loads quickly and updates in real time without manual refresh
• Posting, liking, commenting, and following all persist correctly across sessions
• App passes Play-Store-ready lint checks and installs without errors on physical devices and emulators

Let me know your preferred tech stack, relevant portfolio pieces, and an estimated timeline so we can get started right away.
