Summary
I am an electrical engineer who naturally pivoted to data because I realized the biggest impact was in reducing the number of claims through product data, not just hardware. At Hanwha Qcells, my job required me to directly collaborate with data teams to troubleshoot the product claims and boost customer satisfaction. That hands-on experience motivated me to complete the Data Analytics BootCamp, mastering SQL, Python(Pandas, SciPy, Seaborn) and Tableau. I bring the critical rigor of engineering combined with new analytical tools. I'm ready to apply that blend to deliver actionable insights and improve business performance.
