Remind myself when building data pipelines:

1. Clean data is better than more data.

2. Validate before you transform.

3. Test SQL models, not just the pipeline.

4. Make retries safe and pipelines idempotent.

5. Monitor data freshness, not just job status.

6. Document assumptions — future you will thank you.

Remember: A successful pipeline moves data. A reliable pipeline delivers data you can trust.
