Sam Lazarus
CTO
Sam is a third generation Mathematician-turned-Programmer. He has been programming since he was a child, and working as a Software Developer for over 15 years. He is most passionate about finding elegant solutions to complex problems, and the raw empowerment derived from converting imagined experiences into fully realized code. He has grown from a junior programmer to a team lead; managed everything from UX-centered redesigns to open-ended R&D; developed software for custom hardware platforms; built analytics environments; written tech patents; and learned more tech stacks than he cares to count.
Widely published on topics related to optimization, robotics, and artificial intelligence, Alex is a creative innovator on the forefront of applied sciences. Prior to joining Integrus, where he leads AI and machine learning innovation, Alex developed technology related to robotic motion planning, preference learning, and task allocation with broad applications to industries ranging from autonomous driving to aerospace. Alex is passionate about making connections between seemingly disparate fields to gain additional insights.
After studying Mathematics at the undergraduate and Master's level (Concordia University and McGill University), Electrical Engineering at the Master's level (Concordia University) and Robotics at the doctoral level (the University of Waterloo), Alex has come to the conclusion that when it comes to math, there's always more worth knowing.
