Lead developer for two 3D-TeleImmersive Games:

Released Open-Source Software: Multi-Monitor ViewerJan 2015

Freelance Software EngineerMay 2014 - Jun 2014


Developed software that can be used
1. to operate multiple cameras in a synchronized manner
2. as a multi-view video recorder and player and
3. to calibrate a multi-view camera setup,
including intrinsic and extrinsic parameters. The software was developed in C++, C++/CLI with OpenCV and boost and supports an arbitrary number of camera devices.

Freelance Software EngineerJun 2005 - Aug 2005



2003 - 2009

Diploma in Electrical & Computer Engineering

Telecommunications Engineering

The term passive acoustic radar is used here to denote a device set-up able to detect an audio source in space without utilizing any transmitter. For this purpose, a microphone array was used for audio signal capturing. Via digital signal processing the direction of the incoming audio is identified, giving an estimate for the location of the audio source. Moreover, the radar's software was able to perform audio source recognition utilizing machine learning and pattern recognition techniques.

Involved in design and construction of 3 printed circuit boards (PCBs), developed software in C for Texas Instruments’ TMS320C6711 DSP and user interface software for the PC connected to the PCBs in C++/CLI for visualization and parameterization of the radar.

Sep 2007 - Oct 2007

Internship in the Electronics Engineering Faculty of Nis, Serbia

Undergraduate student

Developed simulations in order to determine bit error rates for signal transmission over wireless and satellite channels. Studied error correction codes. Algorithms were developed in C and MATLAB.
