About

I’m a performance digital marketing professional with 10+ years of experience helping brands grow through data-driven campaigns across search, social, display and video. I specialize in optimizing campaigns to drive ROAS and scale spend while keeping CPA in check.

Beyond the numbers, I partner with clients and cross-functional teams to tell the story behind the data, run A/B tests, and translate insights into practical growth strategies. I’m fluent in English and Mandarin and thrive in remote, fast-paced environments.
