Running a business not only aims for revenue growth but also strives to earn long-term customer trust, especially for companies engaged in international e-commerce.

Therefore, I used various visualization tools in Tableau to present essential data analysis reports required for managing e-commerce, providing decision-makers with valuable insights for reference.
