Agile Almanac - Collaborative Task Management System
TypeScript full-stack MERN application with real-time multi-user collaboration and comprehensive property-based testing
Description
Full-stack MERN application with real-time multi-user collaboration and property-based testing.
Problem Solved
Building a multi-tenant collaborative task management system where multiple users can work concurrently in shared workspaces with instant updates, while maintaining data integrity, authentication security, and protection against abuse. Challenges included real-time state synchronization across distributed clients and implementing workspace-scoped Socket.IO rooms.
Architecture
Three-tier layered architecture with real-time event-driven components. Express backend with Zod schema validation at API boundaries. Mongoose ODM with typed schemas and indexes. Socket.IO service layer for real-time broadcasts. Redux Toolkit frontend with Socket.IO client synchronized state. JWT-based stateless authentication with token verification middleware.
