In graffiti,
the challenge is balancing style with legibility.


That same tension defines my approach to conversation and UX design. Finding the essence that needs to be highlighted, then reducing complexity to what matters most.

Marty Hall - Principal Designer

AI Conversation Specialist, Product Design Consultant, & Typographer

Anthropic Certified: AI Fluency Framework & Foundations

  • Cross-modal support design: Defined product vision for unified voice, chat, and help center support for Expedia Group/VRBO, treating it as one continuous conversation across channels.
  • Conversational flow under crisis: Rebuilt the air cancellation self-service flow during COVID, taking completion from 65% to over 95%, a result cited in Expedia's SEC filing.
  • Agent-side conversation tooling: Redesigned the customer service agent interface for single-screen laptop use overnight when call centers went remote, keeping live conversation handoffs working through the disruption.
  • Conversational research loop: Ran call center usability studies and fed findings directly into agent and supervisor-facing tools, closing the gap between live conversations and design decisions.
  • AI-driven conversation logic: Led UX on Oracle's Integration Cloud Agentic AI & MCP server design, translating structured business rules and API logic into conversational flows that agentic AI systems can act on.
  • Multi-brand design systems: Built design system patterns spanning Expedia.com, Hotels.com, and VRBO.com, keeping conversational and support UX consistent across distinct brands on shared infrastructure.
  • From workshops to working product

    I lead collaborative workshops to surface assumptions, align stakeholders, and define use cases before a single screen is drawn. That process shapes the data: what gets collected, what gets surfaced, and what stays hidden. The result is an experience that reflects how people actually think, not just how systems are structured.

    As a Principal UX Designer at Oracle, our focus was on Generative AI, AI Agents, Processing Robots (RPA), and Integration developer tools.

    At Expedia Group we delivered customer service tools across the company's many brands. The experiences we designed cross desktop and mobile, web, and native applications.

    As a member of the Windows Controls and Patterns team I designed patterns for the Microsoft Fluent Design System, Microsoft Edge, Internet Explorer and Windows.

    What does UX look like in the AI era?

    While researching early generative tools like Jasper, Rytr, DALL-E, and Stable Diffusion, I saw an opportunity to align Oracle’s design system with emerging AI capabilities. A few months before ChatGPT’s release, I formed an AI Working Group within the design organization to explore how AI could be included in our design system.

    The group included designers and design managers from across the organization. We met regularly to share discoveries, experiment with prompts, and discuss how generative tools might influence the way Oracle designs, illustrates, and builds products.

    Speaking at Typographics 2015

    In 2015 Roger Black invited me to speak at Typographics. It was an honor to share the stage with type legends like Paula Scher, Seymour Chwast, Ellen Lupton and many more.

    Logos, Letters and Laughs

    When I’m not designing software, I’m usually sketching letterforms, characters, or custom logos like this one for a local podcast.

    My illustration work blends humor, personality, and craft, often combining traditional techniques with digital polish to give each project a distinct voice.
