    I'm a web-developer with 6 years of web development experience (4 years experience with PHP, 2 years experience with Node.js). I'm a fluently with spoken English and located in Russia (in Syberia, Omsk, to be exact). But enough about me - I'm more interested in knowing how I can serve you better! Do you have an existing web application that needs someone to jump in and quickly be able to contribute with bug fixes, performance optimizations, or any other type of maintenance? I'm the perfect person to help your app run as smoothly and efficiently as possible. Do you have a plan for a new web app that you need someone to bring to life? We can work closely together to ensure that things are up and running quickly and as you envisioned it. In my spare time outside of working on the computer I travel as much as I possibly can and I'm also studying the Chinese language.  less

    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
