Available to hire
Hello, I’m Jestaz Yao, an AI Product Designer with 5+ years shipping end-to-end products across web, e-commerce, and LLM systems. I design deterministic AI workflows — multi-agent orchestration, intent taxonomies, policy engines, confidence gating, and structured outputs — and translate them into measurable business outcomes.
Most recent independent work includes Director, a multi-agent supply-chain decision system where an LLM Director routes between deterministic sub-agents. I benchmarked routing strategies against a 30-question eval harness and shipped a citation drilling UX with auditable data trails, a plan → run → reflect agentic loop, and end-to-end product UI.
