Systems and Computing Engineering student from Colombia, focused on Data Engineering and Full-Stack Development. I build ETL pipelines, BI dashboards, and full-stack systems from scratch — turning messy operational data into tools businesses actually use. Currently researching cloud infrastructure automation with Terraform as part of my thesis.
