I need a social-networking web application built from the ground up, delivered as a responsive, browser-based experience. The core feature for the first release is a real-time messaging system: one-to-one and group chats, online/offline indicators, emoji support, and conversation history that persists in a secure database. Authentication, authorization, and data storage should be implemented with scalability in mind so additional features—such as user profiles or a news feed—can be layered on later without major refactoring. I am open to the framework you prefer (React, Vue, Angular, or similar on the front end; Node.js, Django, Laravel, or comparable on the back end), provided the final code is clean, well-documented, and containerized for easy deployment. Please include an API layer that cleanly separates the front end from the business logic, and make sure the database schema accommodates typical social data relationships. Acceptance criteria for hand-off: • A Git repository with all source code, commit history, and README covering setup and build steps • Working Docker (or equivalent) configuration for local and production environments • Demonstrable messaging feature meeting the specifications above, accessible from both desktop and mobile browsers • Basic unit tests for key endpoints and functions • A short deployment guide outlining hosting requirements and environment variables Timeline, milestones, and any preferred tech stack details can be finalized once we discuss your initial approach.
