Client: A leading tech firm in the USA
Industry Type: IT & Consulting
Products & Services: Marketing Analytics
Organization Size: 100+
The Problem:
- Businesses (especially SMEs) struggle to automate their sales outreach, lead management, and content generation effectively.
- Manually handling posts, email campaigns, lead nurturing, and sales team coordination is slow, inefficient, and error-prone.
- There’s also a lack of personalization during online interactions with potential clients.
Our Solution:
- Sales funnel visibility: From post > lead form > meeting scheduling > lead tracking.

- Automated Zoom meeting scheduling and email confirmations.
- Performance tracking: Graphs, analytics dashboards, lead pipelines.
- Built-in approval workflow for content moderation before posting.
Solution Architecture:
1. Frontend (React) handles the web UI:
- Pages: Home, Pricing, Login/Signup, Dashboard (for all roles).
- Dynamic sections depending on user role.
- Communicates with backend via REST APIs.
2. Backend (Node.js Express Server):
- Authenticates users (admin, sales head, salesperson).
- Handles CRUD for tasks, leads, team members.
- Connects to AI server (Flask) for content generation.
3. Flask Server (AI Automation):
- Generates LinkedIn posts, Emails, Avatars.
- Supports content regeneration.
4. Database (MongoDB):
- Stores users, teams, tasks, leads, subscriptions, avatars.
5. Third Party APIs:
- Zoom API (Meeting Scheduling).
- Email SMTP (Notification + Registration OTPs).
- LinkedIn API (Automated Post Uploading).
- Payment Gateway API (Stripe).
Deliverables:
- Fully operational Backend (Node.js + Express).
- Fully functional Frontend (React).
- Flask-based AI Content Generation Server.
- Admin Dashboard, Sales Head Dashboard, Salesperson Dashboard.
- Avatar Creation Module (Image/Video/Audio based).
- Automated Task Assignment Module (LinkedIn, Email).
- Lead Generation & CRM Reporting Panel.
- Payment Integration for Subscription Plans.
- Role-based access control for Admins, Sales Heads, and Salespersons.
- User Manuals for Admin, Sales Head, and Salesperson.

7. Fast Development and Deployment
- Used Vite for fast frontend builds.
- Deployed backend with PM2 and NGINX for stability.
8. Real-Time Notifications
- Implemented Socket.IO for live updates.
- Added fallback polling for environments without WebSocket support.
9. AI Avatar Training
