About this Gig
Slow queries, messy joins, or a report that won't come together? I'll fix it.
I'm a data analyst/engineer with 5+ years writing and optimizing SQL across PostgreSQL, SQL Server, and AWS Athena. Whether you need a one-off query or want to know why your dashboard takes 40 seconds to load, I can help.
This gig is for you if:
- You need SELECT/JOIN/aggregation queries from a plain-English description
- You have a slow query and want it optimized, with an explanation of why
- You need reusable query logic
What you get:
Clean, commented SQL no black boxes A short explanation of the logic so your team can maintain it Execution plan review on optimization requests (before/after) Tested against your sample data before delivery
What I need from you:
- Your schema or sample data
- What the query should answer
- Which engine you're using (PostgreSQL / SQL Server / Athena)
A query that runs isn't the same as one that answers the right question, I ask before I write.
Message me first if your project doesn't fit a package neatly.

FAQ
Do you sign an NDA?
Yes, happy to sign your NDA or use my own before starting.
What do you need from me to start?
Ideally: sample data (anonymized is fine), your current schema (if one exists), and a plain-English description of what the report/query should answer.
