What I'm looking for

I am looking for opportunities that allow me to utilize my data analysis skills in a collaborative environment, focusing on impactful projects that drive business decisions.

I am a Data Scientist with over three years of experience specializing in financial data analysis and machine learning model development. My proficiency in SQL, R, and Python allows me to extract and manage large volumes of data effectively. At TransUnion, I have developed indicators and implemented data transformations to ensure data integrity while presenting insights through intuitive visualizations for stakeholders.

My background includes a BSc in Statistics from Universidad Nacional de Colombia, where I honed my skills in developing and optimizing R scripts for financial data processing. I have successfully conducted performance testing on financial scoring models and created dynamic HTML reports that enhance the clarity of analysis results. My work has consistently improved operational efficiency and accuracy across various projects.

I am passionate about leveraging data to drive informed decision-making and am always eager to explore new methodologies and technologies that can enhance my analytical capabilities.
