I’m building a simple, proof-of-concept social networking app for Android and need a developer who can squeeze maximum value out of a very limited budget. The core of the app is straightforward: • A lightweight email-based sign-up / login flow (Firebase Authentication or a similarly cost-effective solution is fine). • Clean user profiles that allow each friend to add a photo, short bio and basic contact info. • One-to-one and group messaging with text, emoji and image attachments—speed and reliability are more important than fancy extras right now. A scrolling news feed isn’t required at this stage, but I want the architecture kept modular so it can be bolted on later without a full rewrite. Kotlin in Android Studio is preferred for maintainability, though Java is acceptable if you have an existing framework that accelerates delivery. Please keep the UI minimal but modern (Material 3 components work well), use clear code comments, and host the repo on GitHub so I can track progress. Deliverables are: 1. Compilable Android Studio project with source. 2. Signed APK (or AAB) ready for internal testing. 3. Brief README covering build steps, libraries used and future extension points. If you have experience launching lean MVPs and can guide decisions on free or low-cost backend services for chat and storage, that’s a big plus. Let me know your estimated timeline, any comparable apps you’ve shipped, and how you’d structure milestones to keep things transparent within the tight budget constraints.
