About this Gig
Need a specific number out of your data fast and correct? That's exactly what I do.
I write clean, well-structured SQL and Google BigQuery queries to get you the exact report, metric or dataset you need. Whether it's a one-off pull, a recurring report, or fixing a query that's slow or returning wrong results I've got you covered.
What I can do for you:
Custom SQL / BigQuery queries (joins, CTEs, window functions, aggregations)
Reports and metrics: revenue, retention, cohorts, RFM, funnels
Debugging and optimizing existing queries for speed and accuracy
Cleaning and reshaping raw data into usable tables
Why me: 5+ years as a data analyst working with large, real-world datasets. I deliver readable, commented SQL you can reuse not throwaway code.
Not sure how to scope it? Message me first and I'll tell you honestly what's possible and which package fits.

FAQ
Which SQL databases do you work with?
My core is Google BigQuery (GoogleSQL) and standard SQL, so PostgreSQL, MySQL and similar dialects are fine too.
I don't know SQL — can I still order?
Absolutely. Just describe the result you want in plain words and share sample data or your table structure, and I'll handle the rest.
Can you fix a query someone else wrote?
Yes — debugging and optimizing existing queries is one of the most common things I do.
Is my data safe?
Yes. I only need table structure and sample rows, never real personal data, and I'm happy to work on anonymized samples.
