Professional summary

I am a business development manager with a strong interest in the social sector, and I work at the intersection of business acumen and social sensitivity to produce outcomes that mean something.

My core strength is data-driven, full-funnel optimization. At Ainosion Co., Ltd. I helped build a new business line to secure funding for an AI data center, owning the pipeline end to end — from target analysis through to revenue conversion. Most notably, I designed and implemented a B2B corporate sales funnel that pushed monthly revenue to more than 1,000% of the existing B2C level.

I also understand how the social sector talks and decides. Working as a freelance collaborator with Patti Social Cooperative gave me a close view of how differently for-profit companies and nonprofit organizations arrive at decisions. So beyond driving purchase conversion, I can build authenticity into messaging — explaining why an issue is worth caring about and how someone's participation creates real change.

I want to establish the “why” behind a business while holding its social impact in view, deliver tangible results through solid commercial capability, and earn lasting trust with partners.
