What I'm looking for

I seek growth- or product-focused roles where I can lead data-driven user acquisition, own GTM strategy, scale channels, and mentor teams in fast-paced startups or growth-stage companies.

I am a growth marketing leader and founder with deep experience scaling early-stage tech startups and major fintech and platform products across APAC.

As Founder & CEO of a growth agency, I drove market entry and user acquisition that supported Pre-Series A fundraising, halved CAC in a Japan launch, and achieved 10x month‑over‑month sign-up growth for an AI edutech client.

At Kakao Pay Securities and LINE I led data-driven acquisition and retention programs, delivered multi-million dollar inflows and millions of impressions, and scaled products to millions of monthly active users through experiments, localization playbooks, and cross-functional launch execution.

I publish bestselling personal finance content, built a blog to millions of visits, speak publicly on investing, and mentor students—combining analytical rigor with community-focused content and product-minded growth execution.
