TaskFlow — Enterprise Task & Collaboration Engine

TaskFlow is an enterprise-grade, full-stack collaborative task management platform engineered with Next.js on the frontend and an event-driven Node.js, Express, and MongoDB backend. The platform streamlines team productivity through an interactive UI featuring dynamic task workflows, scheduled agendas, overdue tracking, and multi-tier categorization. It incorporates an end-to-end Socket.IO real-time engine providing direct messaging, online status indicators, live delivery receipts, and instant notification broadcasts. On the backend, a robust architecture powers the platform using a custom QueryBuilder for dynamic search, filtering, and pagination, alongside multi-collection MongoDB aggregation pipelines that drive real-time productivity analytics for both users and administrators. Security is enforced through JWT token pairs, Google OAuth 2.0 authentication, Zod validation, role-based route guards, and a CI/CD pipeline deploying updates automatically to AWS EC2 with PM2.
