CRM

WHMCH CRM is a multi-tenant hosting management platform that automates the entire customer lifecycle—from ordering and instant payment via Bkash & Nagad to service provisioning and automated recurring billing. It includes a complete ticketing system, reseller management, and a robust administrative dashboard.

The challenge

Local hosting providers often struggle with manual payment verification and lack of integration between billing and service activation. The challenge was to build a secure, scalable system that handles high-concurrency billing events and provides a seamless automated checkout experience.

How I approached it

• →Backend Architecture: Developed a high-performance Express/Prisma API with a strict PostgreSQL schema to handle thousands of clients and services with period locking.
• →Nagad Automation: Engineered a sophisticated payment gateway integration using secure RSA signatures, enabling instant service activation upon successful callback verification.
• →Engineered a secure bKash payment gateway integration using RSA signatures, automating instant service activation and reducing checkout-to-activation latency to near-zero.
• →Real-time Dashboard: Leveraged Socket.io for live notifications and support ticket updates, ensuring staff can respond to critical issues immediately.
• →Client Area: Built a glassmorphic, responsive Next.js frontend with Framer Motion for a premium, snappy user experience.
