Project Management App Stack (React, WebSocket, PostgreSQL, Redis, Docker) overview

A collaborative project management application inspired by tools like Linear and Asana. React with Zustand provides a responsive, real-time UI where changes propagate instantly via WebSocket connections managed by Socket.io. PostgreSQL stores the core domain model (projects, tasks, sprints, comments) while Redis handles pub/sub for real-time collaboration, caching, and rate limiting. TypeScript ensures end-to-end type safety from database schema to UI components. Docker Compose orchestrates the full local development stack. The tradeoff is that real-time synchronization and conflict resolution across concurrent editors adds significant complexity — eventual consistency bugs are subtle and hard to reproduce.
