Cloud-Native Task Management System - DevOps Portfolio

A production-ready, cloud-native application demonstrating infrastructure automation, DevOps practices, and platform engineering capabilities using Azure services.

🏗️ Infrastructure & DevOps Focus

This project showcases enterprise-level DevOps and cloud infrastructure skills through:

Infrastructure as Code & Cloud Architecture

• Azure Resource Management: Automated provisioning of multi-tier cloud infrastructure
• Serverless Architecture: Azure Functions for cost-effective, auto-scaling compute
• Managed Database: Azure SQL Database with automated backups and scaling
• Global Content Delivery: Azure Static Web Apps with CDN distribution
• Resource Optimization: Cost-effective architecture (~$7/month total cost)

DevOps & CI/CD Pipeline

• Automated Deployment: GitHub Actions for both frontend and backend
• Environment Management: Separate development/production configurations
• Security Best Practices: Credentials managed via GitHub Secrets and Azure Key Vault
• Code Quality: TypeScript compilation, testing, and build validation
• Infrastructure Monitoring: Application Insights integration

Platform Engineering

• Multi-Region Deployment: Australia Southeast (backend) + East Asia (frontend)
• Cross-Origin Security: Properly configured CORS policies
• Error Handling & Resilience: Database retry logic and connection pooling
• Scalability Design: Serverless functions that scale automatically with demand
