Hi, I'm Tiffany.

Product designer and former APM with 6+ years in complex, trust-critical systems.

I specialize in moderation workflows, enterprise platforms, and high-stakes decision design. I've shipped AI-assisted products and am PMI-certified in AI product management (CPMAI).

Recent Projects

  • Verdict AI Product Design
    Trust & Safety · AI/ML

    Rebuilt a real moderation system 3x; final version reduced reviewer decision friction through evidence-first design.

  • Notification System Product Design
    Enterprise SaaS

    Designed a 3-layer notification system across 7 domains, aligned 12 stakeholders on shared alert logic.

  • Review Workflow Product Design
    B2B SaaS

    Redesigned a broken enterprise workflow; reduced ongoing bug backlog from ~100 story points to a handful per sprint.

  • Roommate Matching Product Design
    Consumer · Marketplace

    Reframed a listing problem as a trust problem; ~1% conversion, ~10% of estimated ceiling — gap was market density, not UX.

Earlier Work

Previously I've worked on biotech SaaS, startup products, and public-sector platforms across regulated, high-stakes domains. My earlier work includes government data visualization platforms and mobile apps that scaled to hundreds of thousands of users.
