Email douglasrizzom@gmail.com
Summary I am an AI specialist with a background in software engineering, working with natural language processing, large language models, computer vision, and reinforcement learning. I worked as an AI Research Specialist at Samsung, specializing in digital health solutions for wearable devices. I also automated citrus orchard monitoring at Adroit Robotics using computer vision techniques. My PhD, funded by CAPES, centered on cooperative multi-agent reinforcement learning using graph neural networks. I have extensive experience in robotics competitions, focusing on developing object detection systems for the robots. I've also worked as a consultant and have publications in the area of educational assessment and computerized adaptive tests.
