Slow Query Optimisation

About this task

This HR software company for law firms (5,000+ employees) is looking for a senior SQL & ETL Support for a single piece of work with a fixed scope and a fixed price. Rewrites queries and adds indexes or partitions.

It is a self-contained job: scope, checklist and price are agreed before you start. The company sells subscription software, so deadlines follow release and billing cycles.

The company prefers a person who can come to Kingston for kickoff and the final review; the rest is remote. 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.
• The finished deliverable in the agreed file format, with sources and assumptions listed
• One round of edits after the company's review is included
• A 20-minute walkthrough call, or a recorded screen share if you prefer

How the work runs

• Day 1: kickoff call and access to the files
• Days 2 to 5: the work, with questions answered the same day
• Last day: delivery and a short walkthrough

Duration: about 10 working days. Accepted when the company contact confirms the deliverable against the written checklist. One round of edits is included.

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 CAD 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.
