September 2025 — Azure/AppService: Delivered two major features focused on improving CI/CD integration and build reliability in proxy environments. 1) GitHub Actions Sidecar Workflows Documentation: comprehensive docs detailing how to attach sidecar containers to App Service for Linux using code-based and container-based workflows, including setup, authentication, deployment, and verification; deprecated outdated templates. 2) App Service behind proxies: Builds behind TLS-inspecting proxies: enabled successful Oryx builds by installing the proxy's public certificate into the Kudu trust store via a new app setting; accompanying proxy documentation updates and blog post revision. No major bugs reported; however, included stability-focused fixes (e.g., updated grep script, minor fixes, and title cleanup) to improve maintainability. The work improves deployment reliability, simplifies sidecar-based patterns, and expands enterprise proxy compatibility. Technologies/skills demonstrated: GitHub Actions, Linux App Service, Oryx builds, TLS interception handling, Kudu trust store customization, and developer-focused documentation.
