Slow Query Optimisation (SQL)

About this task

This contract research organisation in diagnostics (201–500 employees) is looking for a specialist SQL & ETL Support for a single piece of work with a fixed scope and a fixed price. Rewrites queries and adds indexes or partitions.

The company has a deadline, no one free to own it, and wants a person who has done the same job before. It works in life sciences, where documents are versioned and reviewed in a fixed order.

The work is fully remote. Any location in United States works, with a few hours of overlap with the team's day. Evenings or weekends are fine, as long as the agreed weekly output is there.

What you deliver

• Speed up the ten slowest warehouse queries and report before and after run times.
• A 20-minute walkthrough call, or a recorded screen share if you prefer
• A final note stating what was checked and what was left out of scope
• The finished deliverable in the agreed file format, with sources and assumptions listed

How the work runs

• Day 1: scope confirmed in writing, files shared
• Middle of the period: draft shared for early feedback
• Last day: final version and handover note

Duration: about 10 working days. Accepted when the output matches the agreed checklist and the sample check passes; the recruiter confirms by e-mail.

Tools

How you get paid

• The company prepays Deftridge before your first hour, so payment does not depend on a late invoice.
• Deftridge pays you in USD after the company confirms the hours or the deliverable. The payment date is written in your task agreement.
• You work as an independent contractor: you report your own income, and your recruiter sends the statements your accountant needs.
• You never chase the company. Questions about money go to Deftridge.
