Hi,
My name is Jakub, I've graduated IT in 2008 and made 3 postgraduate studies including .NET, PHP and databases.I'm also Linux geek. I've been developing databases and managing database servers for last 5 years.
Mainly I work with PHP and Mysql, but I'm also familiar with Postgresql, Oracle, Mongodb, I had some experience with DB2 too .
First of all : do you want someone to work remotely right ? Cause I turned into freelancing to be able to be on my own. I started my own company where I have second geek in case I'm off for vacation or when we do bigger projects. This way you can be sure somebodys always taking care of your servers. I have a company registered ( for tax and medical reasons ) but I act more like a freelancer, but if you need any kind of NDA or agreement - no problem.
Can you tell me what's your server structure / setup, which vendors are you using and what operating systems ? How many servers/databases , what kind of work do you need to be done - is it managing, maintaining, setting backups, writing frontend/backend applications, all of above ?
From description you gave "depth knowledge of php database management" ... php and database management are 2 different things, so maybe you have some homemade PHP scripts to manage your dbs?
Anyway if you give me more detailed job description I can give you more feedback, but with my experience I can deal with preety much anything. If I can't - I will learn quickly, this is how it works in this business . regards
