Hi, I’m an Android developer with experience in Java, Firebase, backend-connected apps, and secure account flows. I can build the authentication properly with validation, password recovery, session handling, and a clean interface that works well across current Android devices. Before I give you a final schedule, I need to understand what users will do after they sign in, since that will define the backend and screen structure. Do you need email login, phone OTP, social login, or a combination of these?

Hi,I noticed your main priority is **secure user authentication** rather than just building another Android app. Getting login, session management, and backend communication right from the beginning will make the application much more stable and easier to scale later. I'd like to understand your complete app flow before writing a single line of code so the architecture stays clean and future features can be added without major changes. I have one suggestion that could simplify your authentication flow while improving security and reducing maintenance. I'd be happy to explain it in a quick chat. Could you share: * Do you already have the UI design and backend APIs? * Or are you looking for complete development from scratch? Let's have a quick 5-minute discussion before you finalize a developer. Even if we don't work together, I'll share my suggested architecture for your app, which might help you avoid common development issues. Looking forward to your message. Thank you!
