DATA ANALYST
Claudia Cervantes
Data Analyst building analytics pipelines, dashboards, and data insights with Python, SQL, and BI tools.
About
I bring a background in CRM, operations, and cross-functional coordination across cultural organizations, nonprofits, and government environments into data analytics, with a focus on turning complex datasets into clear, useful insights. Through projects in Python, SQL, Power BI, Tableau, API integrations, and AWS cloud analytics workflows, I’ve built experience in data cleaning, exploratory analysis, dashboard design, and storytelling with data.
My portfolio reflects a mix of analytical and business-facing work: from messy HR data audits and global well-being dashboards to music data pipelines and interactive Tableau projects. I’m especially interested in roles where analytics supports decision-making, process improvement, and clearer communication across teams.
