About the blog author

I’m a seasoned UNIX/networking engineer and programmer. Nowadays there’s “devops” term which does closer describes my usual role in the projects. Recently I’ve decided I also should (resume) blog in Russian, so here it is: ru.etcinsider.com

I’m open for collaboration and still looking for job opportunities allowing me to express my knowledge and experience. High load is welcome.
