    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  less
