Economist · Analytics Engineer · Data Analyst Available for work

I turn raw data into metrics teams can actually decide with.

I'm Emilio, an economist working in data. I spent two years building KPI systems, dashboards and automations for one of Argentina's largest consumer-goods companies — working around a closed ERP, moving the team from manual spreadsheets to repeatable pipelines in Python, SQL and Power BI.

Since then I've been expanding from analysis into the systems behind it: extracting data from APIs and other sources, transforming and modeling it with dbt and SQL, and keeping it refreshed automatically. Most of my work sits in that middle layer between raw data and the dashboard.

I enjoy working across that entire process, bringing together data engineering and analysis, combining a strong technical foundation with an economist's way of thinking about data and a designer's eye for how the results are presented.

01 — Projects

Selected work, written up as case studies.

02 — How I approach projects

Three principles behind everything I ship.

Understand

I come from economics, so I start with the business question: who needs this data, what decision it supports, and what success looks like. Most data problems are actually definition problems.

Design to scale

I build the simplest solution that works today without creating problems for tomorrow: with clear data models, idempotent pipelines, and documentation that others can actually use.

Keep learning

I keep expanding both my technical and communication skills. Economics taught me to reason about decisions; Power BI, SQL, Python, and data engineering taught me how to build systems; design and marketing sharpen how I explain and present complex work.
