My working career is quite interesting that I have been building my career focusing digital convergence marketing and advertising from diverse industries more than 20 years.I started my career as a software engineer in Samsung Electronics. This experience in Samsung really help me be special marketer who really understand tangible technology and manage creative, innovative campaign using it. I had worked for Samsung and SIEMENS as a engineer, marketer, sales director for 16 years and successfully launched many new product campaigns for local market and also global market as a key account director. After Siemens, I loved being called on to utilize his knowledge and experience for evolving digital advertising business by VINYL I. It seems to have scheduled for my next step and final destination. I joined VINYL I in 2011 and have successfully led integrated marketing campaign for international and local account like Intel, Nike, Microsoft, Samsung, Naver, Hyundai Motors, SM as a chief operating officer and business officer.
