Hello everyone, my name is Quynh Duyen. I am a last-year student of Le Quy Don gifted high school and also a pre-student of Greenwich University Viet Nam. I have expertise in marketing and operation: Marketing skills are essential to attract and retain customers, increasing brand awareness, and driving sales. It involves researching the market, developing marketing strategies, creating and implementing campaigns, and measuring their effectiveness. Operational skills, on the other hand, are important to manage the day-to-day activities of a business efficiently. This includes managing inventory, logistics, production, and customer service. In this competition, I hope that I can improve and develop my skills, also widen my social network. Besides, I hope that I can contribute to society, and make the world better.
