Cloud Servers Expert | Senior Linux Administrator...

Ukraine - Last active: 2 days ago - Tests: 5 - Portfolio: 2

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. Technology Expertise: Operating Systems: Ubuntu, Debian, CentOS, Gentoo, CloudLinux, OpenBSD, NetBSD and FreeBSD Cloud Hosting: DigitalOcean, Linode, SoftLayer Web servers: NginX, Apache Database Servers: Mysql, Percona, MariaDB Mail Servers: Postfix, Exim, Dovecot Stack installation and optimization: Wordpress, Magento, Opencart, PHP and accelerated by Memcached and Varnish Skills in programming and scripting: - Bash Service description: - Linux server administration, problem-solving, performance and upgrades - Amazon Web Services (EC2, Route 53, Cloudfront, RDS, S3, SES) - Server Management for CentOS/Debian/FreeBSD servers on Web-projects based on PHPEmail Server - Nginx install, upgrades, troubleshooting and performance optimization - Apache install, upgrades, troubleshooting and performance optimization - PHP install, upgrades, performance troubleshooting and performance optimization - MySQL install, upgrades, performance troubleshooting and performance optimization - Website migration - LAMP / LEMP speed optimization - Magento speed optimization - Wordpress speed optimization - Joomla speed optimization - Drupal speed optimization - Varnish setup and tuning - Maintenance, configuration, white-listing, spf, dkim, high load delivery etc. - Google page speed, site speed and web server performance tuneup

Jordon Baade

Web & Technology Consultant

United States - Last active: 5 days ago - Tests: 13

Hello! I'm an English speaking critical thinker and problem solver living just outside of Grand Rapids, MI. (EST) In my 14 years of experience I have filled many roles. I've been tech support, virtual assistant, project manager, designer, analyst, marketer, software engineer, and business owner. I'm happiest when I'm able to help someone leverage technology to better their life or business. My goal here at oDesk is to find clients needing someone to work on their new projects, whether it be a small blog redesign or a complex web application. I take each project on as if it is my own and focus on delivering a great product on time, and within your budget! I would love to talk to you about your specific problem and try to see if we're a good fit! Notes: I prefer fixed price jobs and primarily charge by the day; hourly rates require me to spend a lot of time itemizing and tracking that I could spend focused entirely on you and your problems. Have a large problem you need help on, but not sure who to trust with it? Before starting on any journey it’s wise to plan ahead. I offer a Roadmapping service as a way to help you understand where you’re going, how long it will take, how much fuel (budget) you should expect to use, and what risks face us along the way. After our session, you’ll have a clear and concise roadmap that will help you solve the problems you or your business faces as quickly, safely, and economically as possible. This session is a great way for us to build trust so you can hand over your large project without any worries.
