· Store all secrets in Azure Key Vault and keep dependencies patched with GitHub Dependabot

· Maintain audit logs, change management records, and data handling controls that support internal and external compliance audits

Quality & Delivery

· Ship through GitHub pull requests, code reviews, and GitHub Actions CI/CD pipelines to Azure App Services
