Hi, I’m Igor Ratajczyk, Eng aka @IRatajczyk.

Control Engineer.

I’m interested in ✨Computer Vision Systems✨ and Reinforcement Learning for Continuous Control. I do enjoy Julia.

I'm look forward to collaborating on projects covering Vision Transformers, GANs and High Performance ML for edge devices.

📫 Should you be interested in collaboration or have any doubts about my projects (both Github and non-yet-publised ones) please contact me directly: [email protected]
