Technical Consultant | Expert in Retail Media Integrations & E-Commerce Ad Tech
Hi, I'm Yu-Cheng (Ethan) Keng - a technical consultant specializing in retail media integrations, e-commerce ad tech, and data migration. I'm currently a Sr. Technical Solutions Specialist at Criteo in Tokyo, and I've worked across Tokyo and Taipei. I'm fully trilingual in Japanese, Mandarin, and English, and fluent in Taiwanese.
Outside of work, I love building side projects, exploring AI tools, and playing chill-pop & folk guitar.
