I want to launch a lightweight collaboration space where distributed teams can talk in real time. The first milestone is a clean, reliable messaging and chat experience—think channels, private threads, @mentions, unread indicators, and searchable history—delivered as a responsive web app (React, Vue or similar is fine) backed by a secure, scalable API. Authentication must support email/password and OAuth (Google at minimum), messages need to store safely (PostgreSQL or MongoDB), and WebSocket-style live updates should keep the UI snappy without constant polling. Please containerise the stack with Docker so I can deploy easily to AWS or DigitalOcean. Down the road I may add file-sharing and task-management modules, so design the architecture with clear, documented endpoints and modular front-end components. For this phase your deliverables are: • Source code in a private Git repo • A running demo link or Docker compose file proving “one-command” spin-up • Brief setup & API docs Clean code, concise commits and open communication will be key; if this first release goes smoothly, there’s more feature work right behind it.
