+# MRP Sourcing Application - Portfolio Showcase
+
+A comprehensive Material Requirements Planning (MRP) sourcing system demonstrating expertise in procurement operations, supply chain management, and full-stack application development.
+
+## 🎯 Portfolio Overview
+
+This project showcases real-world procurement experience through a sophisticated MRP sourcing application design. Based on hands-on experience managing daily procurement operations for 200+ SKUs, this system demonstrates deep understanding of:
+
+- **Procurement Operations**: Daily MRP report generation, supplier relationship management, bulk ordering strategies
+- **Supply Chain Analytics**: Real-time inventory tracking, lead time analysis, automated reorder calculations
+- **Technical Implementation**: Full-stack architecture, database design, performance optimization
+
+## 📊 Key Portfolio Components
+
+### [Executive Dashboard](./portfolio/executive-dashboard.md)
+High-level KPIs, critical alerts, and strategic procurement metrics with real-time performance tracking.
+
+### [Daily MRP Report](./portfolio/daily-mrp-report.md)
+Operational procurement workflow demonstrating the daily process of managing inventory levels, supplier orders, and production commitments.
+
+### [Supplier Performance Analysis](./portfolio/supplier-analysis.md)
+Comprehensive vendor management insights including performance scorecards, risk assessment, and strategic partnership recommendations.
+
+### [Stock Flow Visualization](./portfolio/stock-flow-diagram.md)
+Detailed inventory movement tracking showing the complete lifecycle from purchase order to consumption.
+
+### [System Architecture](./portfolio/system-architecture.md)
+Enterprise-level technical implementation including database design, API architecture, security, and deployment strategies.
+
+## 🏭 Real-World Application
+
+This system design reflects actual procurement experience including:
+
+- **Daily Operations**: Processing MRP reports, managing supplier relationships, coordinating with production teams
+- **Strategic Initiatives**: Supplier consolidation, cost optimization, risk mitigation
+- **Process Improvement**: Automation of manual workflows, performance tracking, exception handling
+
+### Core Business Logic
+```
+Stock Status = (Available + Holding + Incoming - Expired - Rejected) / Min Stock
+Color Coding: Green (>80%) → Yellow (60-80%) → Orange (40-60%) → Light Red (20-40%) → Red (<20%)
+```
+
+## 🛠 Technology Stack
