Overview

A practical, opinionated playbook for designing data systems that ship.

The Data Systems Playbook is a structured toolkit for engineers and analysts building real data systems. It does not teach you SQL — it teaches you how to structure, name, operate, and scale a system from a single laptop all the way to a managed warehouse.

How to use this
Pick a deployment (Local, Cloud, Railway, Snowflake), follow the system design flow, copy the templates, then operate from the runbooks.

What you get

  • One canonical bronze → silver → gold mental model.
  • Four reference deployments with the same shape.
  • Strict naming conventions and schema templates.
  • Validation, logging, and runbook patterns.
  • Copy-paste folder structures and Python skeletons.

Who this is for

  • Solo data engineers building from scratch.
  • Analysts graduating from spreadsheets to pipelines.
  • Architects standardizing patterns across teams.
Philosophy
Boring is good. Consistency beats cleverness. Same shape, different scale.
