• Manage secrets and configuration using Azure Key Vault, managed identity, and App Service settings
• Monitor health with Azure Monitor and Application Insights
• Use AI-assisted development daily (code generation, refactoring, debugging, repository analysis, documentation) and review/test all generated code before merging
• Own testing for delivered features (unit, integration, API, end-to-end) so QA receives stable builds
• Work with business users to clarify workflows and turn feedback into working features
• Participate in sprints, code reviews, releases, and production support
• Document work and perform knowledge transfer to internal engineers
