What I'm looking for

I'm looking to grow in a data analytics role where I can support senior analysts and business teams, improve reporting and dashboards, monitor key metrics, and apply Excel, SQL, Power BI, Python, and AI-assisted tools to real business problems.

At Tracts, I collect, clean, and organize data from multiple sources, build Excel and Power BI reporting, and investigate anomalies in operational and financial metrics. I also write SQL queries using SELECT, JOINs, GROUP BY, and CTEs while documenting sources and processes for traceability.

I've built projects including a Neurovault REST API analysis of 17,216 records, a SQL-connected business KPI dashboard, and customer segmentation analysis using Python and SQL. With a Biomedical Engineering background, I bring quantitative problem-solving, bilingual Spanish and English communication, and a practical interest in AI-assisted analytics.
