My published technical articles on Kubernetes, Azure DevOps, PostgreSQL, cloud observability and Microsoft Graph. Each entry links to the original publication.
I trace a tenant-isolation failure to the PostgreSQL role that owned the tables, and explain how to test row-level security with the application’s actual runtime identity.
I examine why Kubernetes Secret synchronization left two pods with different process environments, and show how a deployment check verifies required variable names in every pod.
I trace a .NET RabbitMQ client’s high CPU use to a TLS protocol mismatch, using thread stacks and the first bytes exchanged with the broker.
I examine how drizzle-kit 0.30.4 handled PostgreSQL partitioned tables, why its interactive prompt stalled CI, and how the migration workflow changed.
I trace two Elastic Agent metadata failures on AKS through Azure identity, cluster discovery and the collector’s handling of empty values.
I inspect Classic release snapshots that retained retired Helm and image names after a cutover, then cover dependency cleanup and checks of the current workloads.
A missing probe executable restarted a working container. I explain the different jobs of Kubernetes liveness and readiness checks, including workloads that consume messages in the background.
I examine how an Outlook recurring-series edit produced separate Microsoft Graph update and create notifications, and how correlation, retries and cancellation checks affect the reservation integration.
I describe consolidating duplicate Azure DevOps delivery definitions with run parameters, build tags and stage conditions, including the routing checks that keep modules separate.
