About me


I am a versatile software developer with experience in designing and building software for highly scalable and high-performance applications. Involved with multiple complete product cycles, from inception to prototyping,  development, testing to release. Experience in taking start-up ideas from concept to reality.
I have a huge web development experience (more, than 10 years). I work a lot with Yii2 framework and I really like to work with this technology. I can work with MySql, MongoDB, and other databases.

I can work with cache systems (Memcache, Redis), with third-party software (Sphinx search and other). I know different APIs (social networks, maps, and so on), can do your own API for your project.

I can manage any Linux servers (VPS\VDS or Cloud solutions, like AWS EC2), I use Linux every day in my job like the main system (I don't work with Windows), any config is not a problem for me - Apache, Nginx, PHP installation, some security configuration (firewall [ufw\iptables], ClamAV antivirus, Fail2Ban and other), I can do any updates, upgrades and so on.

Front-end development is not a problem too (I can work with html\css, javascript, jQuery, AJAX, React technologies, can use different CSS frameworks - bootstrap, materialize CSS, etc) Any serious, difficult, and high load big systems - it all is not a problem for me.

I had relocated job positions in Canada and UAE (office jobs with a team), experience in different roles in Russia (office IT jobs), and long experience of a remote job. Also please look at my CV here:

Feel free to write any questions and write about any your offers, I can review it all.
Looking forward to work with you. Thank you.
