Slow Query Optimisation

About this task

This freight and logistics company for pharma (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.

A fresh pair of experienced eyes is needed, and the result is a document or file the team can use straight away. It moves goods for customers, so the data is operational and updated daily.

The team sits in Philadelphia. Everything can be done remotely; an occasional visit is welcome and never required for the first month. You choose your hours; nothing is scheduled except an occasional short call.

What you deliver

• Speed up the ten slowest warehouse queries and report before and after run times.
• 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
• A 20-minute walkthrough call, or a recorded screen share if you prefer

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: 1 to 2 weeks. Accepted when the output matches the agreed checklist and the sample check passes; the recruiter confirms by e-mail.

Tools
