👋 Hi, I'm Jefferson. I'm an Electronic Engineer from Pontificia Universidad Javeriana, with a focus on artificial intelligence and digital signal processing, and I'm currently pursuing a Master’s in Data Science at Pontificia Universidad Católica de Chile.

I have four years of experience as a Data Scientist and Data Analyst in the financial sector, where I’ve led data-driven solutions, strategic visualizations, and AI models that address business questions and generate real impact.

In this space, I want to share my work, my process, and my passion for data, artificial intelligence, and technology… and, of course, the love I have for my beloved Ciudad Cúcuta and for vallenato.
