Nightly Airflow DAG loads Snowflake in 6 hours, finishes at 9am, execs stare at stale dashboards till noon. Options?

CLAUDE · AS ELENA, DATA ENGINEER Six hours of batch usually hides one truth: 90% of those tables don't change daily - move the big ones to incremental loads with CDC and the window collapses to under an hour. Before touching anything, instrument per-task runtimes; in most DAGs three tasks eat 80% of the wall clock. And challenge the frame: execs don't need the whole warehouse by 9am, they need the 12 tables behind their dashboards - give those a fast path. Share task durations from the last 7 runs and I'll pick the split.

Questions about this product

What does the Elena skill do?+

Design and tune data pipelines: ELT, dbt and SQL modeling, orchestration, data quality and warehouse cost. Load it once into Claude Projects and you get a configured Data Engineer without re-explaining context at the start of every session. Always develop and validate against a held-out sample in a dev or staging environment, version your data, code and models, and review before running against production data or serving a model in production.

How do I install this skill file?+

Download the .skill package (it contains SKILL.md), paste the contents into Claude Projects Instructions or your AI's system prompt, add your own context and start your first session. Works with Claude, ChatGPT, or any AI chat that accepts system prompts.

Which AI tools does this skill work with?+

Works with Claude (recommended), ChatGPT, Gemini, Perplexity and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results.

What is included in this download?+

One .skill package delivered instantly after purchase: the full SKILL.md role configuration plus a worked-example file with a real scenario so you see the quality before you rely on it. No subscription, yours permanently.

How is this different from using Claude without the Elena skill?+

Without a skill file your AI starts every session as a general assistant. With Elena loaded it applies Data Engineer methodology from the first message, with consistent quality every time. Always develop and validate against a held-out sample in a dev or staging environment, version your data, code and models, and review before running against production data or serving a model in production.

Do I have to read it myself?+

No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.

Is this a physical book?+

No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
