Hi, I’m Leticia.

A UX Designer and Content Strategist based in Phoenix, Arizona. T²Wire_UX (through the wire) is my brand identity - it’s an ode to an anime (Serial Experiments), AI, data, and interaction.

  • I prototype, test complex use cases, and collaborate with subject matter experts to architect seamless, journey-aligned interactions across diverse digital modalities.

  • I conduct user research and behavioral analysis to decode what users actually need, where they get stuck, and how they behave, taking the guesswork out of design by turning qualitative and quantitative data into actionable insights.

  • I design content frameworks that optimize information architectures for both human audiences and generative search engines. By embedding performance metrics and sentiment tracking into the governance model, I ensure that content structures dynamically surface the highest-value information to users at the exact moment of intent in their journey.

  • I architect end-to-end digital experiences using JSON schemas, rich metadata, visual hierarchies, and WAI-ARIA standards to align with user mental models and ensure seamless programmatic readability. By prototyping integrated UI and content layouts, I analyze user interactions to refine structural paths, optimize generative engine discovery, and eliminate friction across the entire customer journey.

My Portfolio

Agentic AI Alignment

Role: Conversational Designer

Problem: ServiceNow’s enterprise generative AI platform faced critical deployment barriers: multi-turn context drift, ungrounded responses, and susceptibility to adversarial prompt injections. Simultaneously, an escalating taxonomy bottlenecked the Human-in-the-Loop (HITL) data curation workflow, stalling feature validation and product time-to-market. The challenge required designing guardrails for user trust while optimizing internal model training pipelines.

Process: Developed gold-standard datasets, engineered adversarial guardrails, and aligned engineering teams around data taxonomies.

Outcome: Calibrated HITL evaluation UI, driving a 25% increase in cross-functional production throughput.

UX Writing for AI

Close-up of a smartphone displaying a Google search results page with a focus on the 'Analytics' section.

Problem: Google Gemini required massive volumes of highly constrained, gold-standard human-alignment data to mitigate model regressions, safety failure modes, and edge-case behaviors in high-risk query categories.

Process: Engineered thousands of precise training data points, stress-tested model outputs for vulnerabilities, and formulated global documentation to scale ethical AI standards across international teams.

Outcome: Expanded Gemini’s safety guardrails and accelerated data pipeline training velocity by standardizing alignment and annotation workflows across global curation teams.

  • A table listing ten usability heuristics for user interface design, including system status visibility, match with real world, user control, consistency, error prevention, recognition over recall, flexibility, aesthetic design, error recovery, and documentation. The source is cited as Nielsen Norman Group.

    Heuristics

  • A computer screen displaying a navigation map with route lines marked in pink, purple, and orange, and a menu on the right side with options for route guidance. The background map shows the United States with cities like Chicago, Denver, and Los Angeles. Another screen below shows a menu with apps like Map, Navigation, Radio, and Media.

    Heuristic Analysis of Design

  • Screen page titled 'Setting routes & locations' with section 'Severity Rating: 2'. The page contains instructions and tips related to navigation and setting routes for Starbucks and football stadiums, including troubleshooting and customization guidance.

    Heuristic Analysis for Task

  • Flowchart titled "Set destination for U of A Football Stadium" with 13 steps for using Google Maps on iOS to navigate to the stadium, including activating the app, searching, and starting directions.

  • A person sitting in front of a computer monitor displaying a virtual driving scene during a navigation usability test in a room with large windows and fluorescent lighting.

    New List Item

  • Screenshot of a navigation usability test questionnaire titled 'Appendix D: Post-test questionnaire - Qualitative data' with multiple questions about user experiences with a system, including searching for destinations and features like navigation and favorites in a vehicle system.

    New List Item

  • Screenshot of a navigation usability test report titled 'Appendix C: SUS Questions'. It includes three graphs showing responses to questions about ease of use, complexity, and need for technical support regarding a navigation system. There are textual summaries below the graphs and a link to a Google Forms survey at the bottom.

    New List Item

  • A scanned document titled 'Navigation Usability Test' with sections on product, objectives, participants, procedure, and timeline, discussing a navigation interface for Hyundai's in-vehicle infotainment system testing.
