A creative programmer and a heavy Linux user. Started tinkering with computers at age of 13. Since then had a variety of experience in systems programming (C/C++), OS administration (Linux, Windows, Mac), scripting (Bash, Perl), and web (LAMP, Python+Django, HTML+CSS, JavaScript). For the past 5 years main interest lies in front-end development of web applications, JavaScript, and everything JavaScript related (Node.js, Electron, Gjs, etc.).

I believe in the future of web interfaces to just about everything you can imagine! JavaScript is getting it's grip on all major domains of human online interaction, and I will be there to harness all of the new possibilities. I am continuously looking into new ways to unleash the hidden potential of The Language That Can - of the language JavaScript!

Another area of interest for me is working with C/C++. Building applications involving computer vision, real-time video processing, 3D rendering, and system programming in general. IoT (Internet of Things) and hardware (embedded PCs, robotics, flying drones) are two domains where I participated on some very interesting projects in the past.

Blockchain! The potential game changer for the human race. Let’s see what you can do ☺
