Sergei Kozlov


Netzke & ExtJS

Sergei Kozlov’s coding past goes through a lot of C/C++, some PHP, a little bit of C#.NET and Java, straight to the blessings of Ruby and JavaScript. In fact, discovering Ruby-on-Rails and Ext JS (along with OS X) back in 2007, was a kind of rediscovering a coding geek in himself.

His career path starts with Applied Maths/Computer Science Master degree back in 1998 (Minsk, Belarus), followed by a year of research work in the area of image processing (Aachen, Germany), 3 highly demotivating years of coding at Philips Consumer Electronics (Eindhoven, the Netherlands), 3 years of research in the area of multimedia networks at Philips Research (same place), one and a half year of doing Rails/Ext development at Innovate IT Logistics Services (Amsterdam, the Netherlands), and, finally, a joyful switch to freelancing in 2008.

Sergei’s personality tends to seek more than simply living on one place, so his primary source of life energy, along with doing web-development, is traveling and exploring the world (and himself in its context, if that matters). Sergei loves traveling as much as he does coding.


Netzke was born during a journey around Canadian Rockies, out of necessity for DRY, elegant, component-oriented approach to writing Ext JS applications with Rails. Among other advantages, Netzke provides for incapsulating server (Ruby) and client (JavaScript) code into powerful, extendible, easily reusable widgets.

After many iterations, Netzke has taken form of an open source project that is used by developers around the world.
