SKILLS
ABOUT CHRIS MARAIS
Senior ML Engineer / Data Scientist with 6+ years of experience designing, training, and deploying machine learning systems in production across advertising, transport, and construction. I specialize in turning large, complex datasets into scalable, high-impact predictive models.🧠 Skilled in NLP, vision, and sequential modeling using Python (PyTorch, Sklearn, Pandas) and modern MLOps tools like MLFlow, Dask, and SHAP. Proven track record delivering robust, explainable ML solutions — from real-time event detection (95%+ accuracy) to multimodal ad clustering (CLIP) and CTR/VTR prediction models that optimize campaign performance. Combining research depth with production-level execution, I hold an MSc in Intelligent & Adaptive Systems focused on reinforcement learning. Passionate about building reliable, reproducible systems that connect machine learning research to real-world impact.
