Hi, this is Angel. I'm an analytical professional with a double master's in Finance and Business Analytics and Risk Management from Johns Hopkins Carey Business School. My diverse experience includes roles as a Data Scientist Intern at Eth Tech, where I leveraged Python, SQL, and A/B testing to enhance user segmentation and marketing strategies, and as a Data Analyst Intern at the Center for American Progress, where I developed advanced Tableau dashboards and real-time SQL data pipelines. I have also contributed significantly to data-driven decision-making in the restaurant industry as a Data Science Analyst at Veggienius in Taiwan.Leveraging these experiences, I am well-equipped to turn complex data into strategies that drive business growth. I am currently seeking a full-time data analyst role where I can bring my skills to a dynamic, growth-oriented organization.
