I am a guru in web and desktop development.

I have a long track record of projects in web:
- development of websites from scratch;
- customizing existing web solutions (securing poorly written scripts, extending functionality of existing scripts, front-end redesign, CSS/JS bug fixes etc);
- implementing plugins and themes for popular CMS ( Wordpress, Drupal, ModX).

I am an expert in development for Windows OS:
- installers of any complexity;
- Windows services;
- parsers/scrapers;
- shell extensions;
- browser add-ons;
- network utilities etc

There are 4 rules I follow in my work:
1) I have used to do projects of high quality and my reputation is the most important thing to me;
2) I try to avoid conflicts with my clients;
3) If I bid a project, be sure I'll be able to do it within a specified time frame or faster;
4) I don't bid projects if I doubt or not confident
