I will fix broken data pipelines and cut slow, costly cloud workflows

Yes. The Basic tier is exactly that: I diagnose the root cause and explain clearly what's wrong before fixing it.

Yes, I build the system that you run from time to time.

Often, yes — through query/transform tuning, restructuring, and right-sizing resources. Actual savings depend on your setup, so I give you an honest before/after picture rather than overpromising.

Yes. Performance bottlenecks are identified and optimized where necessary.

I implement diagnostic logging first to isolate the real issue before applying fixes.

Usually read access to the code/logs and the relevant environment. You control access, and I follow least-privilege practices.

Python ETL, Airflow/Prefect, AWS, BigQuery, Databricks, Snowflake, Microsoft Fabric, SQL, and common scraping stacks. Send details and I'll confirm.

Only if it's truly necessary. I prefer targeted, practical fixes that preserve what works.

I verify with test runs and validation, and document what changed, so results are clear and repeatable.

Yes — monitoring/alerts can be added, and ongoing maintenance arranged separately.
