    Coding complex systems / project support

    Russia - Last active: 1 day ago - Tests: 5 - Portfolio: 2

    I am working as a web developer for about 10 years. I have started with small freelance tasks and ended with complex web projects. I believe my strong point is ability to understand other's code. I have done many freelance projects involving modification of working projects and that required deep study of code that has been written before. Such a work usually harder than writing a project from zero. I also have wrote from zero two complex CMS with Perl+Mojolicious. One of my large achievements is a complex site written on Perl for a non-commercial international organization (see in portfolio). Last three years I am working on a large online magazine with elements of social network. This requires understanding of Perl, fastCGI, HTML, MySQL. I am constantly implementing new features and fixing bugs that remained from old programmers. I prefer writing in Perl, though I understand PHP and have done many projects with this language. Listed below are my skills: — MySQL — Perl — Mojolicious — PHP/HTML/CSS/JavaScript/jQuery — Nginx configuration — Basics of Linux — dotCloud and other PaaS deployment

    Linux, Networking and DevOps

    United Kingdom - Last active: 8 hours ago - Tests: 8

    I'm an expert in both Linux administration and development. I'm also very well versed in OpenStack including integration, development and maintenance of the many applications in the project. Over the past 4 years, I've developed a large number of projects in a huge variety of languages including Perl, Python, Bash, Zsh, PHP, Go, C, Lua and Groovy. I've also contributed to a number of open-source projects including Jenkins CI and LXD. I've spent the last year working predominantly with monitoring software built on top of Nagios. This has involved initial monitoring implementations/migrations in enterprise environments, providing low-level maintenance/support of these systems and developing methods of monitoring anything which proverbially moves. My networking knowledge is very exhaustive - I maintain a number of Cisco devices in complex infrastructures and have recently finished implementing a virtual networking project for Linux containers making use of VXLAN tunnelling for cross-node networking and route selection. I've also created and implemented a number of network monitoring solutions.
