I’m an economist based in Buenos Aires, working at the intersection of economic analysis, data, and programming. My work combines formal training in economics with hands-on experience in quantitative research, geospatial analysis, natural language processing, and data pipeline development.

I hold a BSc in Economics from UBA (GPA 8.45/10), where my thesis examined debt dynamics and pro-cyclicality using sector-disaggregated data. I’ve contributed to academic research in macroeconomics and machine learning, and I’ve worked as a data analyst and teaching assistant across different contexts.

My projects span economic data pipelines, interactive visualizations, geospatial analysis, and text analysis, all built with real data and real questions in mind. Lately I’ve also been building products end to end, from TTS, a local voice-cloning pipeline for my lectures, to Syndeo, a rental platform I’m currently developing. Its core idea is matching: tenants and landlords state what they need, and only connect when both say yes. You can explore the current collection on the projects page.

currently

  • Decision Analytics Associate @ ZS: applied ML for healthcare decision-making, built on de-identified patient-level data (Python, SQL)
  • Teaching Assistant @ UBA: Macroeconomics II, Quantitative Methods Lab
  • Building Syndeo: two-sided matching for long-term rentals in Argentina, where contact opens only when both sides say yes. Waitlist live at syndeo.casa.
  • Also tinkering with network theory analysis, NLP on Argentine political speeches (Discursos), and maaaaany other cool things.

where it all started

It all started with a simple import pandas as pd, trying to pull Argentina's macro numbers. I'm leaving it here below, as a little gift for you.

beyond work

  • Proudly nerd. I'll spend hours (genuinely, hours) watching videos on the most varied topics: computer science, electrical engineering, physics, mathematics, statistics, you name it.
  • Huge Racing Club fan 🩵🤍, the great passion of my life. If you can't find me working, you'll find me at the Cilindro de Avellaneda.
  • Always building something. I love turning random questions and ideas into small personal projects, usually involving some unnecessarily elaborate solution to a problem I found interesting.
  • In love with Buenos Aires, a city I never get tired of. I love its cafés and late-night bookstores, its food, music, architecture, and, of course, football. To me, it’s one of the best cities in the world to live in.
