- Cabildo of La PalmaData ScientistINTERNET OF THINGS (IOT)January 2024 - January 2025 (1 year)Santa Cruz de La Palma, Spain• Led EDA using Python (Pandas, Matplotlib, Seaborn) and R (ggplot2, dplyr) across 5+ datasets (mobility, night sky, meteorology, air quality). Found ~0.6 Pearson correlation between CO₂ and tidal cycles, suggesting gas buildup tied to tides. This led the Emergency Dept. to revise coastal safety protocols post-eruption.• Created dashboards in Power BI and Tableau for Waste Management and HR. The HR dashboard segmented 1,000+ employees by role and department. The waste dashboard showed recycling unit growth linked to more paper, glass, and packaging collected, justifying changes in the annual report.• Built real-time dashboards in ArcGIS Online, including mobility (vehicles/pedestrians) and a digital twin for CO₂ in Puerto Naos. The Emergency Dept. uses the CO₂ dashboard daily for habitability checks, while others serve internal analytics.• Cleaned and integrated a legacy dataset (3M+ records) into the Cabildo’s meteorological portal. Fixed format issues and created metrics like thermal sensation. Extended public archive from 2022 back to 2016, supporting long-term climate analysis and dashboards.• Proposed a PostgreSQL schema for CO₂ sensor tracking. Automated alias creation from address initials and linked installer/ownership data from private forms to public tables. Ensured consistent, centralized data access for future deployments.
