DS(Dae-Sung) Yu

Jr. Data Analyst, Data Scientist

I'm not just a typical job-seeker.

I'm a freelancer who is eager to create valuable business through data analysis. I majored in Media Engineering at Ajou University. I can use software to extract variable information from web or raw data. After graduation, I was able to gain about 3 years experience using data analysis in IT companies to make practical decisions. These experiences taught me how to apply analysis in a team for marketing. Since 2013, I was responsible as a project manager for the administration of an online game. This project allowed me to develop and refine my problem-solving skills to improve the effectiveness of outcomes. Plus, the game industry involves the the cooperation of multiple fields, so I am experienced in liaising with technology teams to accomplish goals. Now I'm looking to join a part time job as analyst or to get contractsome are analytic tasks.
