Welcome to my world, the world of IT. World, where impossible is nothing. Let me take you to a journey to show you how beautiful this world can be, when nothing besides your imagination constrains you.

I'm a professional, talented and creative software developer. I love to create custom applications in many different programming languages, i.e. C++, C#, ASP.NET, Java, PHP.
I have over 7 years of experience in creating desktop applications and for over two years I'm dealing with creating applications for Web using newest technologies like HTML4/5, CSS2/3 and jQuery.
I have also over four years of experience with working on different database solutions like Microsoft SQL Server 2005/2008R2, SQLite and MySQL, from introducing and managing these solutions to provide safe and reliable work environments to building own applications which use the power of these database engines.

Definetely my passion is to program everything what is programmable, that's why I love to try new, different technologies like programming AVR microcontrollers and programming for mobile devices with Android operating system.

Beyond programming I'm also experienced system administrator specialized in managing medium area networks from setting up client workstations to running large scale production servers. I have over 10 years of experience in managing Windows-based workstations and for over 4 years I'm using Linux and Windows-based servers in a variety of ways, e.g. as a web servers, file servers, print servers, VPN access servers etc.
