Andrés Navarro — Data Analyst · Business Intelligence · ML & AI

Turning data into business decisions that drive revenue growth, cost reduction and process optimization.

📍 Buenos Aires, Argentina  |  🌐 Open to remote opportunities.


About Me

Data Analyst with 2+ years of experience building end-to-end analytical solutions — from ETL pipelines and ML models to executive dashboards — always focused on one thing: measurable business impact.

I don't just analyze data. I identify opportunities, quantify their value in dollars, and deliver solutions that help organizations make better decisions faster.


Business Impact — Selected Projects

Project Business Problem Solution Impact
Supply Chain Optimization 54.8% late delivery rate · $3.9M in losses Delivery risk model + demand forecasting + profitability analysis $13.7M identified
Next Best Offer 97% of customers never return Hybrid recommendation engine · SVD + Content-Based + Business Rules $1.6M revenue uplift
Fraud Detection Undetected fraud destroying margin XGBoost · SMOTE · 97% recall · 284K transactions $55K net benefit
Customer Analytics No customer intelligence · generic campaigns RFM · CLV · Cohort Analysis · 800K+ transactions $1.1M opportunities
Credit Risk Analysis No scoring system · high default exposure Random Forest · FICO Scorecard · AUC-ROC 0.8428 $6.6M net benefit
A/B Testing Framework Decisions made without statistical evidence Z-test · T-test · Bayesian · 500K+ sessions +15% CVR · $10.6M projected

How I Work

  • Business first — every project starts with a real problem and ends with a dollar figure
  • End-to-end — from raw data to production-ready pipelines, dashboards and ML models
  • Honest results — I document limitations, tradeoffs and assumptions — not just metrics
  • Stakeholder-ready — technical depth + clear communication for non-technical audiences
  • AI-augmented analysis — integrating generative AI and automation tools to accelerate insights and build smarter data workflows
