What I'm looking for

I’m looking for a team where I can build AI-driven products from 0→1, run discovery-to-launch cycles, and iterate with strong metrics (funnel, KPI, evaluation) while partnering tightly with engineering to ship real impact.

I’m an AI-native Product Builder focused on turning product discovery into shipped MVPs across RWA (blockchain) and GenAI. At JTG.ai, I led MVP delivery for agentic workflows that generate Lean Canvas, PRDs, and dynamic roadmaps through iterative AI dialogue.

I’ve driven measurable business impact end-to-end, including delivering KPI-driven initiatives that achieved $1.3M YoY cost reduction at Samsung. In parallel, I’ve built full-stack product experiences—like a tokenized seller-financing marketplace—combining Solidity smart contracts, on-chain verification, and compliant off-chain architecture.

Before that, I co-founded and shipped mobile apps by managing outsourced teams and QA, onboarding 100+ retailers and validating PMF through retention. I thrive in ambiguity, use experiments and funnel insights to iterate fast, and build with modern tooling across LLM/RAG, design systems, and developer workflows.
