We are looking to optimise our database, which has over 100,000 rows currently and is expected to exceed 1,000,000. Our queries are complex and take several seconds to execute. This is causing major problems as we have several hundred concurrent users and the server is failing. We require an SQL expert to rewrite the queries (or design an alternative structure) in order to improve efficiency. Please explain your database experience in your bid.

Hi. I have a Computer Engineering degree from Carnegie Mellon and 15 years experience. I've worked with many languages (mostly Java and C), and near all the jobs I've worked had a DB component. I've tended to work on performance and "server-side" issues. I've got a few idea, which I discuss in private mail. I'd want to know your DB type and the extent of the code before committing to the bid I have.
