We launched a site which has lots of complex code to process data, site has been very slow and mysql is bring apache down time to time. We run lots of cron job. We do have developer and server support however I need a person who has done similar work on other large scale site who can analyze and work with our coder, who know inside out mysql and know what causes this kind of problem. You must know how to use server and find out problem.
We are willing to pay right candidate hourly or project basis, please let me know hourly rate. If query or code fixing takes time(most likely you will tell us and we will fix it)
