## Overview

This repository is a collection of DevOps learning projects and portfolio labs, not one integrated runtime product. Its principal demonstrated user workflow is a developer submitting a service name and team to generate a validated service from a template. Other sampled projects expose small HTTP services for orders, jobs, health checks, and metrics. The tree also documents broader infrastructure, Kubernetes, delivery, security, and operations topics, but no README content or implementation excerpts establish their runtime wiring, so those are not expanded into speculative flows.
