    Developer and integrator of web, desktop and system software components based on free and open-source software, unix-like systems and open platforms. Usually known as Mike Kazantsev on the web. I'm an everyday user and passionate developer and contributor of free software, with pretty much whole career spent in this field. Past work includes building and supporting a local web portals from ground-up, managing, scaling and maintaining an infrastructure for large web portals (20k+ pageviews/min), mail systems, hosting platforms, and other services with lots of both public-facing and system-level components. When not on the job, I work at my own open-source software projects (see homepage and github), help maintain a linux distributions, participate in future technology discussions and tinker with web, microcontrollers, new programming languages/techniques. I have a lot of experience with high-level scripting languages, of which I heavily prefer Python, but also worked extensively with JavaScript, PHP, Perl, Lua and many others. Good understanding of database technology, including advanced SQL (PostgreSQL and a bit of Oracle, worked with billing group in a major TelCo), underlying operation and performance implications, some real-world replication and scaling experience. Worked with C on many occasions, but moslty on a smaller projects like optimization and glue modules, tools, simple real-time software (for linux-rt and microcontrollers), fixes, features and patches for larger projects, but never wrote large project in C from ground-up. Almost no C++ experience. Have solid understanding of underlying hardware (incl. current rack server platforms) and some knowledge and experience of assembly programming. Lots of past work with networks (but not much w/ specialized hw) and web.  less
