## Overview

This repository is a career-focused collection of 20 independent, runnable teaching projects—not one integrated analytics or data platform. The principal workflow is a learner exploring a business problem, running a project's analysis or engineering pipeline against its synthetic data, and examining the documented outputs. Engineering examples cover distinct pipeline patterns; they are not stages connected to one another. The README describes notebooks, dashboards, and exports, but those artifacts are not present in the supplied tree, so they are not represented as source nodes.
