What I'm looking for

I'm interested in data analysis that creates social impact and addresses real-world problems, as well as data visualization and data storytelling. I'm also interested in technology entrepreneurship and innovation projects.

At Lactalis Colombia, I designed a Power BI collections dashboard with DAX measures for DSO, overdue balances, and customer segmentation. I also developed custom visuals and a mobile app for the sales team to look up customer accounts.

I automated collections workflows and electronic invoice validation, and reconciled SAP payments against invoices to identify inconsistencies and customer overcharges. In consulting projects, I deployed a real-time people-detection system for Verytel SAS and built regional Power BI dashboards for Regional Insurance Management LAC – VisionFund International.
