What I'm looking for

I’m looking for a data analyst role where I can use SQL, Python, and Tableau to clean, analyze, and visualize data—identify trends, improve accuracy, and deliver practical recommendations in a fast-paced environment.

I’m a Data Analyst with a background in computer science, focused on data cleaning, analysis, and visualization. I use SQL, Python, and Tableau to identify trends, solve operational problems, and deliver data-driven insights in fast-paced environments.

At Correlation One, I analyzed large datasets on the U.S. alternative fuel vehicle (AFV) market using SQL and Excel. I cleaned and transformed raw data to improve quality, built interactive dashboards in Tableau/Looker Studio, and delivered actionable recommendations after applying quantitative analysis to identify trends.

Earlier at UNHCR, I collected, cleaned, and validated structured datasets and ensured high data accuracy (~100%). At Amazon, I resolve inventory discrepancies, improve efficiency (~15%), and support accurate data tracking—backed by strong reporting and data entry habits.
