About Darío
I am a Data Scientist and Business Analyst with a strong background in Psychology, specialized in transforming data into actionable business and people-centered insights. My dual expertise allows me to bridge the gap between analytics and human behavior — turning complex data into clear, strategic decisions.
I help organizations extract value from data through advanced machine learning, predictive modeling, and data visualization. My experience includes building interpretable models (SHAP, PDP, ICE), optimizing pipelines with Python, SQL, and Power BI, and designing ROI-driven simulations to guide investment and business decisions.
I’ve led projects combining AI, behavioral analytics, and business intelligence, delivering measurable impact on decision-making, marketing, and people analytics.
What I offer:
• End-to-end Data Science projects (from cleaning to visualization)
• Predictive analytics and business KPIs modeling
• Dashboarding & storytelling for executive audiences
• Experiment design, A/B testing, and behavioral analysis
Let’s work together to turn your data into insight, and your insight into growth.
