Nelson Cárdenas — Machine Learning Engineer

Hi, I'm Nelson Cárdenas 👋

Machine Learning Engineer · Data Scientist · Electronic Engineer 🇨🇴

I build production-grade machine learning systems, specializing in large-scale time-series forecasting, demand planning, price optimization, and MLOps. My experience spans data engineering, model development, evaluation, and deployment.

I've contributed to forecasting systems covering 45M+ store-item combinations, achieving a 35% relative reduction in forecasting error and a 3.48% increase in order fill rate.

I'm passionate about applied AI, mathematics, art, and building technology that solves real-world problems. I also enjoy sharing what I learn along the way.
