How would you rate your skills in working with MySQL?

I assess my MySQL skills as intermediate (middle). I confidently create and optimize queries, know how to design normalized databases, work with indexes and transactions. I am also familiar with the basics of replication and backups. For example, I can write a query for selection with multiple JOINs and conditions:

SELECT users.name, orders.total
FROM users
JOIN orders ON users.id = orders.user_id
WHERE orders.status = 'completed'
ORDER BY orders.date DESC;
