Slow Query Optimisation · Energy

About this task

This renewable energy developer in wind (201–500 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.

A fresh pair of experienced eyes is needed, and the result is a document or file the team can use straight away. It is an energy business with strict compliance and reporting cycles.

The team sits in Toronto. 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. About 1 hour a week should overlap with the team's day (ET).

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
• 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

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 on the company's written OK. If something is missed, you fix it in the same week at no extra charge to either side.

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.
