Episode 1 of Human Code, a field guide to the corporate predator. Meet Ignis salvator: the engineer who is always first on the scene of every incident — for reasons the post-mortem never asks about. Hero syndrome, observed in its natural habitat.
A Docker container without orchestration is a boat without navigation. This article covers the HELM framework — Kubernetes deployments, Helm chart templating, horizontal auto-scaling, network policies, pod security contexts, and the monitoring integration that ties the entire series together.
The gap between "works on my machine" and "runs in production" is a Dockerfile. This article covers the DOCK framework — multi-stage builds that produce minimal images, non-root container security, Docker Compose orchestration with health checks, and lean image optimization.
Code coverage is a number. Confidence is a feeling. They are not the same thing. This article introduces the PYRAMID framework — unit tests with Mockito, integration tests with MockMvc, ArchUnit architecture enforcement, JaCoCo coverage gates, and the test infrastructure that makes it all reliable.
A microservice without observability is a black box you cannot operate. This article introduces the TRACE framework — structured logging with correlation IDs, custom business metrics with Micrometer, and distributed tracing with Zipkin. The three pillars that make production debuggable.
Traditional thread pools cap at 200 threads eating 200 MB of memory. Java virtual threads handle 10,000+ concurrent operations at 1 KB each. This article covers the ASYNC framework — virtual thread configuration, CompletableFuture composition, parallel fetching, and async bulk processing.
Generic error responses tell your users nothing and your developers even less. This article introduces the CRAFT framework — sealed exception hierarchies, RFC 7807 ProblemDetail responses, multi-layer validation, and a GlobalExceptionHandler that turns failures into useful communication.
Security is either invisible and effective or visible and broken. This article covers the GUARD framework for Spring Security — SecurityFilterChain configuration, role-based access control, CORS policies, BCrypt password encoding, and a test security setup that doesn't weaken production.
