I’m a results-driven Data Analyst with a strong background in administrative management and guest relations. I’m proficient in SQL, Tableau, and data cleaning pipelines that transform complex operational datasets into clear, actionable reporting.

I apply critical thinking and technical proficiency to optimize organizational systems and support executive decision-making. In my portfolio work, I engineered a data-driven conversion strategy for a 5.5 million-row bike-share dataset using SQL (BigQuery), isolating user personas and identifying that casual riders travel 58% longer per trip—then delivering a “Summer-to-Annual” marketing framework to maximize subscription ROI.

I also extract and visualize insights end-to-end, from data cleaning & validation to executive presentation. For example, I mapped audio feature trends from an 85,000-track dataset using SQL and Tableau, creating an executive music production playbook that optimizes track duration and tempo to accelerate release momentum.
