Economist · Master's degree in Data Science · La Paz, Bolivia

I am an economist with a Master's degree in Data Science and over five years of experience in Bolivia's public financial and public investment sectors, at the Central Bank of Bolivia, the Ministry of Economy and Public Finance and the Bolivian Highway Administration. I specialize in financial system regulation and policy, government financial operations and the monitoring of public investment projects, and I apply quantitative and econometric methods to economic analysis, with expertise in structuring and leveraging databases, business intelligence, analytical visualization and process automation. As a researcher, I study Bolivia's parallel dollar market with Markov regime-switching models; I have published 18 opinion articles in Bolivian media and taught training programs on Power BI and cryptocurrencies.
