Data Analyst at InfuseMedia, validating 120+ customer records daily and building SQL, R, and Tableau analysis projects.
United StatesWhat I'm looking for
At InfuseMedia, I verify and validate customer database records, conducting 120+ phone verifications daily and flagging inaccurate or inconsistent entries. I also work with cross-functional teams to review verification patterns and recommend process improvements.
For my Cyclistic Bike-Share Usage Analysis capstone, I cleaned and analyzed 12 months of trip data using SQL and R, then created an interactive Tableau dashboard with three recommendations. In an independent retail analysis project, I used SQL and Python to explore sales and seasonal demand trends and inform inventory recommendations.
My earlier work includes maintaining databases and supporting users at Khuda Services and Logistics, organizing verification data at Vena Solutions, and assisting with backend development at AmaliTech gGmbH. I completed the Google Data Analytics Professional Certificate and am seeking an entry-level Data Analyst role where I can support data-driven decision-making.
