Message

At Grupo Mayoreo / PRISMA, I developed pricing-intelligence analytics across 1,300+ SKUs and margin analysis for 430 priority products. I also developed NLP-based product classification and semantic matching on large import datasets using transformers and embeddings.

I built automated data ingestion, transformation, and reporting services with Python, PostgreSQL, Docker, and Google Cloud Run. As a Data Scientist & BI Consultant at Upwork, I delivered ETL pipelines, SQL analysis, and Power BI reporting for U.S. clients.

I teach Operations Research at University of Carabobo, including mathematical optimization and linear programming. My background in economics and quantitative research also includes forecasting, statistical analysis, and applied machine learning.
