DevPulse : MERN Collaborative Platform
Full-stack real-time collaboration workspace with Socket.io streaming, kanban task state, and RESTful API architecture.
Overview
DevPulse is an engineering team workspace enabling real-time kanban state synchronization, project activity feeds, and instant team chat without page refreshes. Built using the MERN stack with optimized MongoDB indexes and Node.js event-driven architecture.
My role
Full-Stack Engineer — Designed schemas, implemented real-time WebSocket events, built RESTful backend routes, and developed responsive React UI.
Key features
Real-Time WebSocket State Sync
Socket.io bidirectional event bus transmitting board updates, live presence indicators, and instant messaging across concurrent users.
MongoDB Aggregation & Indexing
Custom aggregation pipelines for task analytics and compound indexing for sub-50ms query latency on complex multi-tenant boards.
Secure JWT Authentication & Middleware
Stateless token-based authentication with bcrypt password hashing, refresh token rotation, and granular role permissions (Admin, Member, Viewer).
Responsive React UI with Tailwind
Component-driven interface featuring drag-and-drop task workflows, optimistic UI updates, and responsive layouts.
Engineering decisions
Chose Socket.io paired with Express clustering and MongoDB change streams to deliver instant updates while preserving ACID consistency on transactional task assignments.
Learnings
- Handling race conditions in concurrent multi-user drag-and-drop board state updates.
- Designing robust MongoDB schema structures for nested comments, attachments, and audit logs.
- Optimizing client-side React re-renders using memoization and scoped WebSocket event listeners.
Results
Delivered a responsive full-stack platform supporting concurrent collaborative sessions with sub-100ms real-time event propagation.
