Overview

Developed a complete Sales and Manufacturing CRM system to manage the entire business lifecycle from inquiries to dispatch operations. The system integrates multiple sales channels, automates order processing, and provides a unified platform for managing sales pipeline, products, manufacturing processes, and logistics operations.

Key Features

• Complete CRM System: Comprehensive management of inquiries, sales pipeline, products, manufacturing processes, and dispatch operations in a single platform
• Dynamic Product Attribute System: Flexible product configuration system allowing dynamic attributes and variations without code changes
• Role-Based Access Control (RBAC): Multi-level hierarchy for departments with granular permissions ensuring secure access to sensitive business data
• Multi-Channel Order Integration: Automated order syncing from Amazon, FirstCry, and Shopify using APIs, eliminating manual data entry and reducing operational errors
• Logistics Optimization: Intelligent courier assignment, delivery workflow automation, and real-time tracking to reduce logistics costs and improve turnaround time
• Communication Integration: WhatsApp API integration for instant notifications and Mailgun for marketing and transactional emails
• Cross-Platform Mobile App: Developed internal operations app using Cordova (Ionic framework), deployable as Web, Android, and iOS from a single codebase
• Cloud Infrastructure: Managed deployments on AWS with EC2 for hosting and S3 for secure file storage and media management
• Data Management: Implemented modules for PDF generation, Excel export for reporting, and Excel import for bulk onboarding of historical data

Technologies Used

• Frontend: React.js, Ionic Framework, Cordova
• Backend: Node.js, Express.js
• Database: MongoDB, MySQL
• Cloud Services: AWS (EC2, S3)
• APIs: Amazon Seller API, FirstCry API, Shopify API, WhatsApp Business API
• Email Services: Mailgun
• Document Processing: PDF generation libraries, Excel processing libraries
• Mobile: Cordova (Ionic) for cross-platform deployment

Challenges and Learnings

One of the major challenges was integrating multiple e-commerce platforms (Amazon, FirstCry, Shopify) with different API structures and rate limits. This required building a robust abstraction layer that normalized data from different sources while handling API rate limits and error scenarios gracefully. Implementing the multi-level department hierarchy with RBAC required careful design to ensure permissions cascaded correctly while maintaining security. The cross-platform mobile app development with Cordova presented challenges in maintaining consistent UI/UX across Web, Android, and iOS platforms. Optimizing the logistics workflow involved analyzing historical delivery data to create intelligent courier assignment algorithms that consider factors like distance, capacity, and delivery time windows.

Outcome

The CRM system successfully automated order processing from multiple channels, reducing manual workload by 75% and operational errors by 90%. The automated courier assignment system reduced logistics costs by 30% and improved delivery turnaround time by 40%. The cross-platform mobile app enabled field operations teams to access critical information on-the-go, improving operational efficiency. The bulk data import feature accelerated the migration of historical data, saving weeks of manual data entry work.
