About Matthew D.

I'm a dedicated machine learning engineer with a strong academic foundation, holding a master's degree in computer science (with distinction) from the University of the Witwatersrand, where I specialized in the exciting and transformative field of reinforcement learning. My passion lies in exploring the deep intersections between artificial intelligence and human intelligence, particularly in how reinforcement learning enables AI agents to learn, adapt, and make decisions much like humans do.My most recent role at Ominor allowed me to put my expertise into practice. I served as a machine learning engineer (contract role), where I applied my skills in feature engineering and leveraged programming languages like Python to develop and deploy solutions using Google Cloud Platform. In my previous role as a machine learning consultant at Smartcall, I delved into the exciting world of computer vision, working on target detection and classification problems. These experiences have been instrumental in honing my practical skills and insights into real-world AI applications.Beyond my professional work, I've had the privilege of sharing my knowledge and enthusiasm as a tutor for undergraduate and honours students, specializing in adaptive computing and machine learning. Guiding the next generation of AI researchers and practitioners has been an incredibly rewarding experience.I'm always eager to explore new opportunities, connect with like-minded professionals, and continue pushing the boundaries of what's possible in the world of machine learning and AI. Let's connect and explore the future of AI together!CORE COMPETENCIES→ Data Science & Analysis → Machine/Deep Learning→ Python-Based Model Development → Project Management→ Data Pipeline Design/Automation → Cloud Computing (GCP)→ Predictive Modelling → Business Intelligence→ Software Development → Dashboards Creation→ Complex Problem Solving → Data Visualisation
