Nine years in product design and development, seven as product lead in blockchain and fintech. At Supra Labs I led the team that built SupraScan, an L1 chain's native explorer, from scratch, and defined the API layer its wallet, marketing and ecosystem teams shared. At Formosa Financial, an enterprise-wallet fintech, my research moved the product from B2B to B2C. Now building Deejiar, a consumer AI app, end to end, with a confidence-scored database keeping AI output controllable.
Experience
Product Role
- Consumer AI - Deejiar2026.5 – Current
Founder
- Defined an “inherit, don’t generate” direction: the AI adapts journeys local guides have actually lived, so international travelers tailor one in a tap. Live on iOS and web in Tokyo, Singapore and Taipei.
- Built a dynamic database with confidence-scored validation: places come from human-verified content and routes are computed, not generated, so every itinerary can be followed.
- After launch, recruited local guides city by city to build the platform’s supply side from zero.
- Built on an agent workflow I designed and open-sourced for Claude Code and Codex.
