Summary
I am an emerging Data Analyst with a unique background in Business English instruction, where I spent eight years developing strong analytical thinking by evaluating learner performance, identifying patterns, and improving outcomes through data-informed decisions. My experience working with diverse professionals strengthened my ability to understand stakeholder needs and translate them into practical solutions. I now combine these people-centered skills with technical abilities in SQL, Excel, and data visualization to support data-driven decision-making and performance improvement.
