Hands-on King County housing analysis focused on how property attributes and location influence sale prices.

Performed EDA to explore demographic, geographic, and time-based patterns, then distilled results into clear metrics and visuals that highlight trends and data quality considerations.

Collaborated with five teammates on an operational performance study of flight delays across airlines, weekdays, and airports. Cleaned and validated a 5,000‑record sample derived from 1,050,000+ flights, engineered delay categories and KPIs, and built Google Sheets dashboards to compare airline performance, weekday trends, and airport bottlenecks.

Exploratory analysis of the Kaggle UFO sightings dataset with a Python → Tableau workflow. Cleaned malformed rows, fixed datetime inconsistencies, normalized types, removed outliers, and enriched country fields before exporting a curated dataset. Built an interactive Tableau dashboard highlighting temporal trends, geographic hotspots, and country-level summaries.
