At FUNDACIÓN SOCIAL VIVE COLOMBIA – FUNVIVE 2.0, I collected and processed data from multiple sources using SQL and NoSQL technologies. I produced reports and dashboards with Power BI and Tableau.

I also implemented automation workflows using supervised, unsupervised, and generative machine-learning techniques to optimize data analysis and processing.

At Universidad de los Andes - Colombia, my research included estimating parameters in Be star disk models with Bayesian inference and Emcee. I also worked on rural building detection from satellite images using ArcGIS and a YOLO-type model.

My research has also explored machine learning for protocluster parameter estimation and synthetic data generation for infrared spectra. I’m interested in data science and its applications in astrophysics, sustainability, and insurance.
