I’m preparing to launch a small-scale social networking service and need it delivered in two forms: a responsive website for desktop/tablet/mobile browsers and a dedicated Android app compiled from the same codebase or an equivalent native build. The overall feel must be clean, modern, and intuitive so new users can sign up, create a profile, and start interacting in just a few taps. Core scope • User authentication – email or phone-based signup/login, password reset, and optional social logins. • Admin panel – web based, with role control, user management, basic analytics, and the ability to moderate content. • Security – HTTPS everywhere, input validation, protected endpoints, and secure storage of credentials (hash & salt). • UI/UX – consistent branding, responsive layouts, and smooth navigation that follows current Android Material guidelines on mobile while remaining just as polished in browsers. • Handover – full source code, build/run instructions, and one brief knowledge-transfer session. I’m flexible on the tech stack; React, Next.js, Flutter, Kotlin, Node, Laravel, or similar are all fine so long as the final product is maintainable and well-documented. When you reply, please include: 1. A quick note on relevant projects or portfolio links. 2. Proposed stack and any third-party services you’d integrate. 3. Estimated timeline broken down by major milestones. 4. Total cost and any suggested payment schedule. Feel free to ask clarifying questions—getting the foundations right is more important than rushing features.
