Experience
GUI Application for Programming Radar Chips
A C++/Qt/QML application that helped the user design a radar chip program with a GUI without the need to remember all the machine code instructions and then generate a machine code program out of it. This project also involved some Python and Groovy scripting.
Trading Application
A C++/Qt GUI application for automated stock trading of different stocks in the portfolio. This project included real-time communication via sockets and then transferring this data to the AI module, which decided on the following action.
LX Zeus
http://www.lxnavigation.com/navigation/zeus5/LX Zeus is a navigational device for glider airplanes, which was developed using C++ and Qt.
Lottery Tickets Sales
This is a client application that allows salesmen to sell lottery tickets to customers. Every transaction is sent to a centralized server for approval. The application is property of Loterija Slovenije, which is the main lottery tickets sales company in Slovenija.
Registration of Range Images
This research project application allows user to register 3D data obtained from different viewpoints and create a 3D CAD model. The link is to the article that was published in Computing Journal about the application.
Method for the Selection of Parametric Models in a Data Segmentation Framework
This application was part of a PhD thesis. It demonstrated how the selection of an optimal set of parametric models, fitted to different datasets, works.
Sample Animation in C++
A small application that shows an animated rotating football, which I wrote in C++. No images are preloaded; instead, the application generates everything on the fly. To run this application, the user must install the Qt library.
