Cloud Servers Expert | Senior Linux Administrator

I am an expert in installation, tuning and optimization of the servers and PHP applications such as Wordpress, Magento, Opencart, Atlassian JIRA, etc. I?m usng NginX and Apache servers. I'm a fan of NginX and expertise in this server. My No. 1 goal is to meet my client?s needs, to do the task in time and of high quality. When I work on a new project, I like to communicate with a client, in such a way I can have a clear understanding of his/her vision of the project. The most frequent issue which I face is tuning of Linux servers optimization on which Wordpress, Magento or OpenCart are hosted. My goal is to achieve maximum productivity of the server and to adjust it so that the content will be delivered with high performance and to make the server handle high load of traffic. I?ve accomplished some projects the results of which are impressive: the load of one project was 5000 online unique users, and the total of requests in another project was 50000 for 5 minutes.
