I am a Digital Marketing Specialist with over 5 years of experience in performance marketing, lead generation, and customer acquisition. My expertise includes paid media management, web analytics, conversion rate optimization (CRO), and campaign planning across Google Ads, Yahoo Ads, Meta Ads, LINE Ads, and Microsoft Ads. At an EdTech company, I managed an annual advertising budget of approximately JPY 50 million and contributed to significant business growth through in-house advertising operations, landing page optimization, and data-driven marketing initiatives.

Prior to my marketing career, I worked in e-commerce consulting and sales support, helping online merchants improve sales performance through advertising and promotional strategies.
