We are developing many complex web projects where we are in need with handling the server side with a reliable system admin guy .
- highly knowledge of amazon server products ( EC2, instance types, etc)
- have strong linux knowledges
- ssh handeling via root access
- install libraries for different needs
- check the resources of the server , make sure they are set up properly
- optimisation of the server
- memory management
Because the applications we build are mainly php/mysql/ajax with different frameworks as Zend, CodeIgniter, Symfony 2, cakephp , some little php knowledges will really help.
We would rather to pay by hourly and start a long term commitment with a very very serious guy.
