The most amazing...

...thing I've made is an autonomous poker program that uses Bayesian inference to estimate the opponent's style after just a few hands and win even against humans.


  • R&D Lead Engineer

    2013 - PRESENT
    • Managed the R&D division of the company. Monitored all major R&D projects, reported on progress, and provided technical guidance to keep on track.
    • Worked closely with other researchers on design, implementation, and optimization of the algorithms.
    • Envisioned an algorithm for creating mosaic images from surveillance footage or sets of aerial images. Guided the team to successful implementation of the algorithm.
    • Successfully modernized the code base by porting it to C++11. Made code more secure and less prone to errors and memory leaks.
    • Established coding style guidelines and introduced good programming practices to the team, including pair programming, code reviews, and supported teamwork.
    Technologies: C++
  • R&D Engineer - Sr. Software Engineer

    2008 - 2013
    • Improved the current multi-frame super-resolution algorithm by making it resilient to ghosting effects present at the time.
    • Ported most of company's video processing algorithms to CUDA, including super-resolution, de-blurring, contrast enhancement, frame-rate adjustment, and more.
    • Optimized all above mentioned algorithms and enabled real-time performance.
    • Created a testing framework for video processing algorithms to ensure successful regression testing under change.
    • Ported an extremely challenging MSER feature detector to CUDA (filed a patent).
    • Created a RAII-based GPU memory management system which hides memory allocation latency and enables even more performance.
    Technologies: C++, CUDA, OpenCL
  • Junior Researcher

    2007 - 2008
    Deutsche Telekom Laboratories
    • Researched in the field of computer vision on the problems of real-time human head pose estimation.
    Technologies: C++
  • Software Development Intern

    2005 - 2005
    Faculty of Electronic Enegineering, University of Nis
    • Developed a 3D graphics engine for massive landscape rendering in C++ and OpenGL. The engine was able to render gigabytes of terrain texture data in real time by automatically adjusting level of detail on per frame basis.
    Technologies: C++, OpenGL
