Slow Query Optimisation

About this task

This Series B games studio making educational games (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 is a games studio with release dates that move the whole calendar.

The work is fully remote. Any location in Canada works, with a few hours of overlap with the team's day. Most people do this on weekday evenings; replies inside the working day are not expected.

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
• One round of edits after the company's review is included
• The finished deliverable in the agreed file format, with sources and assumptions listed

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: 2 to 3 weeks. Accepted after the walkthrough. Edits requested within three working days are part of the price.

• You work as an independent contractor: you report your own income, and your recruiter sends the statements your accountant needs.
