ARCHITECTURE & SECURITY

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

Client

Admin Console

React SPA

Role management, routing rules, and reconciliation dashboards.

Agent Workspace

React SPA

Unified inbox, real-time chat, and commerce context panels.

Public Connectors

Webhooks

Ingestion endpoints for WhatsApp, Social, and Web Chat.

Services Layer

Node.js

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.

RESTful APIsSocket.IOWebhooks

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.

BullMQ

Webhook Processing

Ingests raw provider events into Redis queues for fast acknowledgment.

BullMQ

Retry Handling

Exponential backoff for temporary API failures or rate limits.

BullMQ

Deduplication

Drops duplicate webhook signatures before database insertion.

Socket.IO

Live Updates

Pushes new messages and assignment events to agents instantly.

Cron

Scheduled Sync

Cron jobs pulling branch POS data and ecommerce orders periodically.

Cron

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.

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.
