Production Kubernetes Platform with Helm 3 Microservices, Argo CD GitOps & Azure DevOps Pipelines

• Containerized Python FastAPI ingestion engine and React/TS web dashboard.
• Helm 3 Chart with parameterized values.yaml, liveness/readiness probes, and resource quotas.
• Declarative Argo CD GitOps controller automating reconciliation and zero-downtime rollouts.
• Azure DevOps YAML pipeline for chart linting and container vulnerability validation.

Enterprise Azure Hub-and-Spoke Network Architecture with Azure Firewall, VNet Peering & Custom UDR Routing

• Hub VNet with dedicated AzureFirewallSubnet, GatewaySubnet, and AzureBastionSubnet.
• Non-transitive bidirectional VNet Peering to spoke-app and spoke-db.
• User-Defined Routes (UDR) forcing all 0.0.0.0/0 outbound traffic through Azure Firewall private IP.
• Granular Network Security Groups (NSGs) restricting lateral workload movement.

Multi-Stage Shift-Left DevSecOps CI/CD Pipeline with Gitleaks, TFLint, TFSec & Infracost

• 6-Stage production pipeline: Gitleaks ➔ TFLint ➔ TFSec ➔ Infracost ➔ TF Plan ➔ Approval Gate ➔ TF Apply.
• Remote Azure Storage Blob state locking with automated plan artifact validation.
• Zero hardcoded credentials leveraging service connections and environment secrets.

Modular Azure Enterprise Landing Zone Library Aligned with Microsoft Cloud Adoption Framework (CAF)

• 8 Reusable modules: Resource Group, VNet, Subnet, NIC, Public IP, Virtual Machine, SQL Server, and SQL Database.
• Fully validated end-to-end reference architecture (examples/complete) passing terraform validate.
• Standardized resource tagging and governance according to Microsoft enterprise best practices.

Zero-Trust Multi-Tier Application Hosting with Nginx Edge Reverse Proxy & Private Subnet Isolation

• Complete DMZ separation: Nginx edge reverse proxy serving static React SPA with CSP and HSTS headers.
• Backend FastAPI microservice isolated in private network with zero public ingress.
• Docker Compose multi-tier stack, Linux systemd daemon unit, and Azure DevOps release pipeline with Trivy scans.
