Hire the Best Data Visualization Specialists
in Spain

I’m a data storyteller specializing in Tableau and modern BI — building dashboards that feel less like reports and more like products. Over the past 5 years, I’ve delivered 50+ dashboards and 14 end-to-end BI applications across Finance, Retail, and HR. From pipelines processing billions of rows to lightweight self-serve analytics, my focus stays consistent: turning raw, messy data into structured, reliable systems — and presenting it in a way people actually want to use. What sets me apart is the combination of three layers: data modeling, transformation, and visual design — all treated as one cohesive experience. I don’t just build dashboards. I design interfaces for decision-making. No clutter, no confusion, no need for explanations — just clear logic, strong hierarchy, and intuitive flow from question to answer. What I bring: • Tableau, Power BI, Qlik Sense — with a strong focus on UI/UX and visual clarity • End-to-end data transformation: dbt, SQL, Python (from raw data to production-ready models) • Modern data stack: Snowflake, BigQuery, Airflow, Fivetran • Dashboards used by 5000+ daily users • ETL automation saving teams 20+ hours per week • Led large-scale BI migrations (Tableau ↔ Qlik, Power BI → Tableau) • Strong product analytics background: funnels, retention, LTV, experimentation I’m especially interested in work where structure meets aesthetics — where clean data models, thoughtful transformations, and sharp visual design come together into one system that just works. Whether you need a high-impact executive dashboard, a scalable analytics layer, or a full rebuild of your BI stack — I focus on making it not only functional, but seamless. Let’s turn your data into something people actually want to open.
