A scalable MERN architecture for real-time omnichannel operations.
The platform architecture connects React-based admin and agent consoles with Node APIs, webhook receivers, channel connectors, Socket.IO real-time updates, MongoDB data models, Redis queues, audit logs, RBAC, and secure deployment controls.
Frontend & Backend Architecture
A decoupled architecture utilizing dedicated React single-page applications for presentation and scalable Node.js microservices for core logic.
Presentation Layer
Admin Console
React SPARole management, routing rules, and reconciliation dashboards.
Agent Workspace
React SPAUnified inbox, real-time chat, and commerce context panels.
Public Connectors
WebhooksIngestion endpoints for WhatsApp, Social, and Web Chat.
Services Layer
API Gateway
Express routing, rate limiting, and JWT auth verification.
Assignment Engine
Evaluates presence, queue load, and agent skills.
Integration Sync
Pulls order history and pushes chat events to CRM.
Event Logger
Immutable write-append log for all system activities.
Real-Time & Background Processing
To prevent UI blocking and ensure high availability, heavy operations are offloaded to Redis-backed queues, while Socket.IO handles instantaneous state propagation to the client consoles.
Webhook Processing
Ingests raw provider events into Redis queues for fast acknowledgment.
Retry Handling
Exponential backoff for temporary API failures or rate limits.
Deduplication
Drops duplicate webhook signatures before database insertion.
Live Updates
Pushes new messages and assignment events to agents instantly.
Scheduled Sync
Cron jobs pulling branch POS data and ecommerce orders periodically.
Report Generation
Background workers compiling heavy SLA and reconciliation exports.
Data Model Architecture
A MongoDB-based document schema optimized for deep relationships between customers, unified conversations, assignments, and commerce orders.
NoSQL Data Model
Key Relationships
Platform Security & Reliability
Enterprise-grade safeguards ensuring data integrity, authorized access, and high availability.
JWT Authentication
Short-lived tokens with secure HTTP-only refresh mechanism.
Role-Based Access (RBAC)
Strict permission boundaries between Agents, Leads, and Admins.
Webhook Signatures
Cryptographic verification of inbound provider events.
Event Deduplication
Redis-backed caching prevents double-processing of webhooks.
Rate Limiting
API gateway safeguards against traffic spikes and abuse.
Encrypted Secrets
Environment variables and API keys secured at rest.
Immutable Audit Logs
Every admin configuration change is recorded permanently.
Secure Deployment
Isolated staging environments with CI/CD access controls.
Health Checks
Automated probing of services, databases, and queues.
Monitoring Alerts
Real-time Slack/Email alerts for connector failures.
Role-Based Access Control
Fine-grained permissions ensure that operations teams, branch managers, and agents only see and modify data relevant to their specific role.
Role-Based Access Control
| Permission | Super Admin | Operations | Team Lead | Agent | Branch Mgr |
|---|---|---|---|---|---|
| View Conversations | team | assigned | branch | ||
