About Me

/Who Am I

I was born in eastern Serbia in 1979. During my childhood I didn’t have any clear picture of what should I do later in my life. Beside gaming, my love towards computers grew during the 20th century so I specialized in hardware maintenance. I’ve been involved in fiscal policy with cash registers and afterwards started to learn about web development which is also my main occupation nowadays. What started with hardware eventually finished with software.

Some time after that I started my work in marketing and publications niche. I mastered the applications needed for my everyday tasks as an Editor of a fitness magazine. Needless to say that knowing the Windows OS and LAN environment was very helpful.

After many years of hard work, effort and experience I made connections with foreign clients thus moved my interest further towards new web standards which occupies the most of my (free) time lately… along with parenthood.




/What I do

After more than a decade in HTML environment, which still is the essence of the web, I expanded my interest towards CMS platforms such as WordPress and OpenCart. My interests and knowledge are expanding towards new technologies which are always going to be a topic on my blog pages.


WordPress is leading content management system (CMS) based on PHP and MySQL. Features include a plugin architecture and a template system. WordPress was used by more than 27.5% of the top 10 million websites as of February 2017. WordPress is reportedly the most popular website management or blogging system in use on the Web, supporting more than 60 million websites.


OpenCart is an online store management system. It is PHP-based, using a MySQL database and HTML components. It is freely available under the GNU General Public License and it powers over 342.000 eCommerce Entrepreneurs all over the world from corporations to local businesses. The OpenCart Marketplace features 13000+ modules and themes to jump-start, grow and expand your business.


All my work is covered with full support. I can be contacted in many ways over various chat platforms whatever clients prefer (Skype, Viber, WhatsApp, Slack, Email, online contact forms, etc). If you hire me via UpWork website your support is even more guarantied by the terms of their legal agreement. If you have issues with other third party software you can also contact me for free advice.
