Slow Query Optimisation · E-commerce

About this task

This Series B subscription commerce company for children's clothing (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 sells online, so volumes move with promotions and the calendar matters.

The team sits in San Francisco. Everything can be done remotely; an occasional visit is welcome and never required for the first month. Most people do this on weekday evenings; replies inside the working day are not expected. About 1 hour a week should overlap with the team's day (PT).

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

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 when the company contact confirms the deliverable against the written checklist. One round of edits is included.
