I've had the privilege of working closely with Ondrej for three years, and I wholeheartedly recommend him as an exceptional computer vision specialist. Ondrej has been instrumental in our projects, with a key focus on camera and device calibration. His expertise in custom bundle adjustment software and his ability to tackle even the finest nuances and hidden bugs in our extensive data processing pipelines have significantly contributed to our success. He is a true expert in C++ and Python, languages he skillfully employs for both debugging and visualizing 3D and camera-related data. Ondrej has a deep understanding of Linux and edge computing platforms like Nvidia Jetson, making him comfortable in any environment. One of Ondrej's standout qualities is his proficiency in accelerating existing pipelines through custom CUDA kernel development. His methodical approach to problem-solving and concentration in discovering hidden bugs is unmatched. In summary, Ondrej is an invaluable asset with expertise in computer vision, C++, Python, CUDA, and a deep understanding of data processing pipelines. His meticulous and methodological approach to his work makes him a standout colleague. I have no doubt that Ondrej will continue to excel in any challenging role and bring tremendous value to any team. I will certainly contact him when there will be a need for a senior CV developer.
