About

Hi, I’m Takuma Oka—a Technical SEO Specialist with a unique background as a former Aircraft Mechanic (JASDF). I apply the same ‘zero-error’ precision and safety standards from aviation to website architecture, crawling, and indexing. I specialize in large-scale cross-domain tracking, Core Web Vitals optimization, and multilingual SEO (JP/EN/ZH) for the APAC market.

I blend a growth mindset with data-driven testing to drive acquisition, activation, and retention. My strengths include IA/UX optimization, CRO and A/B testing, and building KPI-focused dashboards using GA4, GSC, Looker Studio, and Ahrefs. I collaborate cross-functionally with Product, Eng, and Editorial teams to deliver scalable editorial processes and international SEO operations.
