Founded a couple of open source projects, most remarkable being flamerobin.org, which is now the default administration GUI for the open-source Firebird DBMS. I got really close with people in that community (had beers with most core developers ;) and even presented some papers/sessions at three Firebird conferences. I also run the official Firebird FAQ website at firebirdfaq.org.
Wrote some shareware software available at guacosoft.com. Most successful product is a home-inventory application called Attic Manager.
From 2009 got interested into web space. I created a couple of successful websites for the local Serbian market: slagalica.tv (gaming website, avg. 30k+ visits/day), comp.rs (wordpress hosting), krtica.rs (collecting data from financial institutions using a distributed network of 60+ computers) and carevoblago.com (another game site).
In 2013, focused completely on social-gaming. Built two successful Facebook games with 150.000+ MAU each.
Built a multiplayer strategy game using node.js, HTML5 Canvas, and socket.io: http://gos.bigosaur.com
