How I Built a Data Catalogue From Scratch As a Data Engineer

A lone data engineer at a mid‑size manufacturing firm built a data catalogue from scratch, turning ad‑hoc notes into a structured metadata repository. The organization lacked documentation, ownership, and a data strategy, causing slow, risky deliveries and hidden changes. By capturing learnings daily, identifying patterns, and gradually formalizing metadata, the engineer delivered tangible improvements in data discoverability and risk mitigation. The effort illustrates how "MetadataOps" can evolve organically even in low‑maturity environments.
