Cepelin is an android app that I’ve worked on with my colleges from my (now ex) firm youngculture.  There was believe it or not, eight of us willing to learning something, create an app and have a lot of fun. Couple of meetings with beer, few days working on an “ueberly awesome” idea (cafe, restaurant and event guide) we actually won the golden award on VIP mobile’s Android Challenge.

Members of the awesome team are: Saša Slavnić, Dragan Marjanović, Marko Simić, Željko Gavrilović, Žarko Šušnjar, Igor Popov, Igor Spasić and yours truly.

You can see our icon in the official VIP mobile commercial (27-28th second) :)

And here are the screenshots:

Gradski Prevoz – android app

My third application for VIP Android Challenge 1.0. I’ve created this application with great friend of mine Milan Delibašić.

Gradski Prevoz (Public Transport) helps user in using public transport by providing information on lines, schedules and other useful stuff. Currently supports several lines of public transport in Belgrade, Serbia.

This application (although not fully finished, because we didn’t map all the lines and buses) won the bronze award (HTC Hero)

This application was featured in VIP mobile’s commercial :)

klopaj! for android

My second application for VIP Android Challenge 1.0. Klopaj! lets you search entire Belgrade for the best restaurants. Just enter type of food, or restaurant’s name or whatever you would like and let klopaj show you where it is. You can comment restaurants, added them to your favorites, love them or not. App is powered by klopaj.com website.

This application also won a HTC Tattoo phone, that I’m currently using :)

988 Helper

988 Helper (originally 988 Pomoćnik) is my first Android application it was created for the VIP Android Challenge 1.0 . I’ve worked on it together with my great friend Milan Delibašić

The point is that somebody calls you, and you don’t have that person/number in your phonebook, 988 Helper will find out who is that person using Telekom Srbija’s 988 service. Simple as that :)

Application won HTC Tattoo phone :D

UPDATE: 988 Pomoćnik has been removed from the android market, because Telekom Srbija’s site has changed. Before taking it off this application had more than 3000 downloads. I’ve very proud of that detail :)


I couldn’t think of a better name for this one, but hey, it’s only a school project for my master studies.

I had to implement an app that shows the benefit of using Aspects. So I’ve created an app that downloads pictures from Picasa, using Google’s APIs. Of course, with some aspects behind it (logging and thread pool).

It was finished in September 2009.

Address Space Manager

I’ve finished my bachelor studies with this final project (“graduation project”) that I’ve work with my girlfriend Ivana Vrbić. We implemented “Address Space Manager” for RCUB, that eventually became a part of their NetIIS application.

It was implemented in Java programming language. It purpose is to be used by network admins, so they could scan any (reachable) network to find our all the available devices and their IP addresses and other useful information. We used SNMP protocol to find out all the details we needed.

We both finished with the highest grades, and got our bachelor diplomas in October 2007.


My first java web project, and it was for “Internet programming” class. The goal was to create a college portal so that students could book their time for laboratory tests and exams and pick lab demonstrator. On the other side professor can reschedule groups, set payment checks for lab demonstrators and similar.

It was implemented in Java/JSP/Struts with MySQL as database.

Implementation date:  August 2007.


An interesting mini project for the “Expert systems” class: Verbal arithmetic. On of the most popular is SEND + MORE = MONEY. So what is verbal arithmetic? Basically is a type of mathematical game consisting of a mathematical equation among unknown numbers, whose digits are represented by letters.

Here we weren’t focusing only on SEND + MORE = MONEY, there was unknown number of variables. And only addition was supported.

As most of the school projects, it was implemented in java, in june 2007.

Performance of Computing systems

For “Performance of Computing systems” class I was supposed to implement a real time simulation of a processor with two hard disk drives and compute various statistical data. Not very interesting to be honest. It was done, as usual in Java, back in june 2007.

Hospital manager

Another interesting school project: Create a hospital manager application in Java, and use MSSQL for database.

Unfortunately it was a command line application, because the main goal was to create an efficient database scheme. This was my first experience with MS SQL Server and TSQL.
