Casey Lab

Data Engineering Labs

Applied ETL, automation, and platform reliability patterns.

This sandbox is for practical delivery patterns across SQL, SSIS, Azure Data Factory, Databricks, and .NET tooling. Every entry focuses on repeatability, production safety, and faster troubleshooting.

Lab Scope

Production-grade thinking in a safe test space.

ETL
Pipeline design
Ops

Code
Internal tools

Playbooks

Reusable runbooks and delivery patterns.

Short guides that can be reused for enterprise data operations.

ETL release checklist

Pre-prod validation, deployment gates, rollback criteria, and post-release checks.

Incident triage flow

Fast root-cause routing for failed jobs, missing files, schema drift, and SLA risk.

Change governance

Ticketing, peer review, and release notes that keep production stable.

Sandbox

Current experiments and reference builds.
