Android App & Game Development

@Abdullah926

I’m a Unity developer with 4+ years of experience building mobile apps and games with shared systems like authentication, social integration, and in-app purchases. I can handle both the app and game using a clean architecture, ensuring seamless account sync and smooth user experience across both. I’ve integrated SDKs for Google/Facebook login, payments (IAP), and Play Store deployment, and will deliver fully documented source code, APKs, and support through final submission. Happy to discuss the best tech stack for your combined ecosystem.

With over X years of experience as a full-stack developer, I am extremely well-versed in every aspect of the project you outlined. My forte lies in iOS and Android app development, and I have shipped numerous apps in the past which demonstrates my skill and expertise. I’m adept at integrating SDKs for authentication, social media, and payments, and this aligns perfectly with your project requirements. In terms of games development, I have extensive know-how in Unity, Cocos2d, and Godot engines. Having indeed worked on projects where games and traditional apps shared common account systems before I'm confident that I can deliver according to your needs. I would also like to add that my previous clients have always appreciated the clean, well-documented source code I deliver - something that is vital for the long-term maintenance of your projects. A satisfying post-development experience is equally important to me, so I’m dedicated to providing you with APKs for both app & game that work flawlessly along with their respective source codes, comments, and README files.

You’re building an app + game that need to work as one system. That only works if the backend, auth, and payments are set up properly from day one. That’s where I come in. I’ll build a shared backend for authentication (email, social, guest) and payments, then connect both the Android app (Kotlin) and the game (Unity) to it so users move seamlessly between them. I’ve worked on Android apps and interactive projects with: • Social login and sharing flows • Google Play billing (IAP + subscriptions) • Systems where multiple products share the same user base What you’ll get: • App + game ready for release • Clean, documented source code • Smooth Play Store deployment support If you want, I can quickly map the architecture based on your game idea before we start. Let’s start.

Hi, This is an interesting setup—you’re not just building an app and a game separately, but creating a shared ecosystem where authentication, user data, and monetization need to work seamlessly across both. From experience, the main challenge in projects like this is keeping everything connected cleanly: A centralized auth system that works across app + game (including guest → registered flow) Smooth social login and sharing integrations Reliable in-app purchases/subscriptions without breaking user experience I’ve worked on similar builds involving: Unity-based games with backend integration Mobile apps with secure authentication and API-driven systems Payment and social SDK integrations My approach would be to first establish a solid backend/auth layer, then connect both the app and game to ensure consistency and scalability. Quick questions: Do you already have a backend/API in place, or should that be built from scratch? What type of game are you planning (casual, multiplayer, etc.)? If this aligns, let’s connect and map out the architecture before starting—I can help you execute this end-to-end smoothly.
