ML Engineer

Киев · $3000 · 4 года опыта · Upper Intermediate

I was part of computer vision project. My main responsibilities were: prototyping, developing and maintaining video-analytics detectors in Python and C++. Function of each detector is to warn or prevent particular kind of alarming event. I analyzed pedestrians behavior with classical ML algorithms, wrote bunch of detectors for video surveillance system like: unusual motion, clean zone, tampering, loitering, abandoned objects, object tracking with re-identification and so on. Currently I'm working for leading provider of broadband solutions that deliver video, voice and data to communications providers but want to improve my ML skills and grow as expert in this domain.
