# Jamie Byun > AI Product Manager & Builder | ex-DocuSign | AI UX, LLM, AI Agents | AI Agent Orchestration · LLM Integration · Data-Driven Product Strategy | Claude Code, Copilot, Cursor Location: San Francisco Bay Area, United States Profile: https://flows.cv/jamiebyun Senior Product Manager at the intersection of AI, marketplace, and growth. - I build consumer-facing products that scale, from ambiguous ideas to measurable business impact. Over the past 5+ years, I’ve led end-to-end product strategy across marketplace expansion, personalization, growth experimentation, and monetization, partnering closely with engineering, design, data, and business teams. At Yogiyo, an 8M MAU delivery marketplace, I drove high-impact initiatives used by millions: Launched an intent-personalized Quick Order experience, predicting reorders from user behavior, generating $45M ARR uplift through A/B testing and funnel analytics Scaled a new delivery vertical from 0 to $26M in annual revenue, coordinating 100+ cross-functional stakeholders Owned checkout and subscription flows, improving conversion and retention through experimentation Led English localization efforts to reduce support friction and improve global accessibility My approach is rooted in Human-Centered Design (University of Washington) and shaped by early UX experience at Sonos and DocuSign. I combine strong user intuition with rigorous execution and data-driven decision making. Recently, I’ve been focused on AI-native product development, building with tools like Claude Code and Cursor, and exploring how LLM-powered workflows can enhance consumer experiences, from interview prep to health tracking. I’m especially interested in products where personalization, search, marketplace dynamics, or AI-driven decision-making are core to the value. If you're building in this space and need a PM who can turn ambiguity into impact, I’m open to connecting.
