    Experienced in developing distributed systems, network services and backends for websites in Perl. I can develop complete website solution from Linux server installation and administration to complex modern web-interface in JavaScript (except graphical design). I'm developing software since 1989. I work as Perl/Web Developer since 1997. Development priorities: code simplicity and clarity, reliability, security, efficiency. I've experience with Apache and Nginx web servers, MySQL and NoSQL databases, Mojolicious and Backbone.js frameworks, Perl/HTML/JavaScript/CSS, FastCGI, non-blocking I/O, event-oriented and concurrent programming, complex parsing (fetching, parsing and processing complex data from thousands pages on hundreds websites every minute), service-oriented architecture, distributed computing, developing Perl modules, automated testing, … I work as Linux admin since 1994. Experienced in developing own Linux distribution from scratch (2001-2004). I've strong focus on security and since 2004 use Hardened Gentoo Linux. Experienced in developing large systems (50000+ man/hours) as Systems Architect and Senior Developer. Experienced Team Leader and Manager for small team (about 10 developers/testers). Also I'm author of many articles (mostly in Russian) and have small experience (about 6 months) as Top Manager in software company (about 200 employee). Since 2001 I'm working as full-time freelancer. I never agree to work which must be done quickly in exchange for quality. I like to do things in the Right Way and prefer simplicity and minimalism. I'm interested in tasks which should be implemented using OS Inferno and language Limbo (which usually mean distributed and/or highly concurrent systems). I'm looking for long-term business relationships with customers.
