Enterprise CRM Platform

The Challenge

The organization struggled with fragmented data across spreadsheets and legacy tools. They needed a unified, secure system to bridge Marketing (Leads), Operations (Tasks), and Finance (Invoicing) with granular permission levels.

System Metrics

Implementation

Architected a decoupled microservices system using FastAPI for high-concurrency performance. Implemented strict Role-Based Access Control (RBAC) via custom JWT middleware to handle sensitive enterprise data.

Optimized complex analytical queries using SQLAlchemy and materialized views. Designed a type-safe, fully responsive frontend architecture to ensure desktop and mobile stability.
