Message

I independently built and deployed an automated data pipeline using Python, SQL, and Power BI. It cleaned and structured raw data, triggered SQL updates, and refreshed dashboards on demand, bringing manual reporting effort close to zero.

At Registraduría Nacional del Estado Civil, I maintained data integrity in large citizen databases, with zero errors during high-volume census and electoral operations. At Uber, I tracked logistics and performance data to guide service decisions while maintaining a 4.9/5.0 rating.

I completed a 392-hour Advanced Data Analytics and Business Intelligence bootcamp and hold Google's Professional Cybersecurity Certificate. My toolkit includes Python, SQL, Power BI, Tableau, and Looker Studio.
