About
A career spanning engineering, management, and GTM.
YOSHI has built a cross-functional career across engineering, management, and GTM. After working as a backend engineer at an Software company on business improvement projects for major financial institutions and system integrators, he worked independently across sales support, corporate website production, and IT event operations.
He later joined a startup as a director, leading generative AI initiatives including LLM chatbot development and internal AI strategy planning and execution.
Strengths
Structuring business challenges, applying global AI insights, and validating ideas through rapid prototyping — the shortest path from problem to product.
Connecting founders' ideas to working products — from AI/tech selection through MVP implementation. Engineers often miss the business angle; consultants rarely reach implementation. I bridge that gap alone.

Translating cutting-edge AI practices from Silicon Valley into implementation strategies for Japanese enterprises. Going beyond English fluency to the level of "so how does this actually work for our company?"

Building LPs and prototypes in days, not months — turning hypotheses into running products so decisions are made on what works, not on what's written in slides.

Articulating the problems founders themselves haven't put into words yet — root causes, structures, causality. Implementation skill is wasted on the wrong question. I'm trusted with framing the question first.
