Hi, I'm Sebastián.

I work with data: analysis, reporting and automation.

I'm a Data Analyst at POPS. I prepare and analyze data, build reports in Power BI and automate how they reach the people who use them. Here I document the projects I've worked on and what I've learned.

How I work with data.

Most of my work follows the same steps: get the data in order, find what matters and share it with the people who need it.

More about my approach
From scattered records to a report that reaches every store, without anyone copying and pasting.Illustrative animation · No real figures or internal data
From information to action
Three steps from information to action Information is organized, explored visually and shared for action. All shapes are illustrative, not real measurements.

Organizing information creates a clearer starting point for the questions that matter.

About me.

I like understanding what the data says and finding ways to make it useful. Most of my work is analysis and reporting; web development and automation help me get those results to the people who need them.

I began at POPS as an intern from January to May 2026. Today I work in Data & Analytics, connecting dashboards, web tools and automation.
