    I am pursuing a double major in Data Science & Statistics and Quantitative Economics with a minor in Finance. I am a curious type of person, a typical ENFP-er (Campaigner), so my interests are diverse and broad, from Data, Technology, and Science to Economics, Finance, and Consulting, to Education and Social Work, to Sports, Music, and Entertainment. I am always in a state of getting ready to ask, find, and learn new things and new skills. That open mind has helped me meet outstanding people in different fields and catch valuable opportunities that came to me. I will keep that with me in my journey ahead to achieve and learn more and more about, and beyond, this world. Learning, for me, is a life-long process. I am highly skilled and practiced in data analysis, creative content writing, excel accounting and finance, project organizing, and Mathematics and standardized tests (ACT/SAT/AP) tutoring. I am actively looking for a job/internship in Data Engineer and Data Scientist positions in both technology and financial consulting areas. Additionally, I am also working as a freelance tutor and creative content writer.
