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, and API-based 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.
