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.

    Russia - Last active: 1 day ago - Tests: 14

    Over the last 10 years, I'm network administrator, architect and CIO in various hosting and ISP companies. Due this I have relatively good skills in Linux/BSD, virtualization, routing and shell/perl-scripting. My previous professional bio can be divided into 4 independent parts: - from 1990 to 1996 -- system programming for PCDOS (Assembler, C) - from 1996 to 1999 -- HPC programming and teaching for MPI, PVM, HP/Convex - from 1997 to 1998 -- programming for DSP controllers - from 1999 to 2003 -- programming, administration and teaching for Lotus Notes/Domino My current targets are: - programming in C, C++ and Perl - building and managing networks - building and managing virtual environments I prefer opensource whenever it's possible, but without zealotry. I think that the best opensource platform is Linux, but without zealotry too. In my opinion, the best Linux distro is Ubuntu LTS, but without any religious zealotry again.
