Nicolas Ruiz Buitrago

I’m a data analyst with 2+ years of combined experience across the energy, financial, and digital marketing sectors. I work hands-on with SQL, Power BI, and Excel to validate data quality and turn complex datasets into clear, actionable insights for business stakeholders. I’ve built dashboards and reports that drive decisions, automating data workflows and communicating findings effectively across technical and non-technical audiences. Highlights include process automation delivering up to 25× efficiency gains, and consolidating 19,036 records into 1,396 canonical items—a 92.7% reduction in redundancy that improved data governance and traceability. In recent roles, I delivered end-to-end BI solutions, executive dashboards, and automated reporting processes for operational performance monitoring. I bring a strong bias toward measurable impact—improving visibility, reducing validation time, and supporting high-stakes business and compliance outcomes through reliable data.
