Senior Software Developer at Zebra Technologies · machine vision and machine learning in C++ · Montréal
I’ve written production C++ for seven years, at Matrox Imaging and then Zebra. I developed 2D vision and machine learning algorithms for the Aurora Imaging Library, Zebra’s machine vision SDK, evaluated deep learning models for object and text detection, and fitted the algorithms to smart cameras. Today I also work on generative AI.
