Slow Query Optimisation

About this task

This mobile games company making mobile puzzles (5,000+ employees) is looking for a manager 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 a games studio with release dates that move the whole calendar.

The company prefers a person who can come to Utrecht for kickoff and the final review; the rest is remote. You choose your hours; nothing is scheduled except an occasional short call. About 1 hour a week should overlap with the team's day (CET).

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: 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: 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.
