DevOps | Linux Administrator | NginX | AWS | Cloud Architectures
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 use Memcached, Varnish, w3total cache plugin for WP to improve performance and optimize server.
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.
After server optimization I perform load testing using apache benchmark and siege. These utilities give the chance to estimate traffic which the server will be able to handle.
I use Amazon Web Services, DigitalOcean or Linode cloud providers and recommend them to my clients. Their servers are rather reliable and fast.
I use Postfix or Exim in the bundle with Dovectot as an e-mail server. For Inbox control it is necessary to adjust DKIM and SPF for email. For secure connection - SSL certificates adjustment is essential.
