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.
Work Experience
R&D Lead Engineer
MotionDSP
- Wrote automatic optimizer of data-intensive algorithms in C++. Code automatically generates multi-core and vector optimizations.
- Worked closely with other researchers on design, implementation, and optimization of computer vision, image processing, video processing, machine learning, AI, and deep learning algorithms.
- Envisioned an algorithm for creating mosaic images from surveillance footage or sets of aerial images. Guided the team to the successful implementation of the algorithm.
- Successfully modernized C++ codebase by porting it to C++11, C++14, and C++17. 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.
- Led 3D GIS project development - similar to Google Earth with real-time video stream rendering on top of the 3D globe.
- 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.
R&D Engineer - Senior Software Engineer
MotionDSP
- Improved the current multi-frame super-resolution algorithm by making it resilient to ghosting effects present at the time.
- Ported most of the company's video processing algorithms to CUDA (GPGPU), including super-resolution, de-blurring, contrast enhancement, frame-rate adjustment, and more.
- Optimized all the 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 an RAII-based GPU memory management system which hides memory allocation latency and enables even more performance.
Junior Researcher
Deutsche Telekom Laboratories
- Researched the problem of real-time human head poses estimation in the field of computer vision (CV).
- Implemented a novel approach to this problem. Used OpenCV, C++, and Linux.
- Published paper on the proposed method in the Automatic Face and Gesture Recognition conference.
Software Development Intern
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.
- Optimized engine performance to achieve real-time.

Source in C++
• Symbol x(0);
• Symbol y(1);
• auto f = (sqrt(sqr(x) * 2.0f + sqr(y)) + 1.0f);
They can also evaluate them, get derivatives, and apply them to a data collection, possibly in parallel.
