Verified Competencies Demonstrated by Andres Matiz Lopez

By completing this curriculum to the standards of the IxDF Educational Codex, Andres Matiz Lopez has demonstrated mastery of how to:

  • Plan and run moderated usability tests, then turn findings into prioritized fixes, grounding design decisions in evidence.

  • Conduct heuristic evaluations and benchmarking to catch problems early, while they're less costly to fix.

  • Run and analyze card sorts to structure navigation around how people actually think, so users can find what they need without guessing.

  • Design and interpret A/B and multivariate tests to prove which version performs.

  • Build conversion funnels and run root cause analysis to pinpoint where users drop off and why.

  • Quantify interaction efficiency with Fitts' Law and the Keystroke-Level Model to make frequent tasks measurably faster.

  • Audit interfaces against WCAG accessibility standards and optimize for search (SEO) to widen reach and reduce legal exposure.

  • Design usable forms, navigation, and visual layout using layout grids, visual hierarchy, and Gestalt grouping.

  • Apply persuasion and trust techniques, from credibility cues to emotional journey mapping, to build the trust that lifts conversion.

  • Build personas that keep real users at the center of every decision, as well as the requirements and prototypes that turn insight into tested design.

  • Integrate UX into Agile delivery using the Parallel Streams approach and design maps, keeping design and research one cycle ahead of development.

  • Use the psychology of attention and perception to guide the eye to the most important elements first.

  • Apply human error theory to design interfaces that help users avoid mistakes and recover from them.

  • Distinguish conceptual and domain models and use them to provide a shared understanding across a team.

  • Use the inverted pyramid and readability metrics so users can find and act on content quickly.

  • Design dynamic interfaces with AJAX that update smoothly without disorienting users or compromising SEO and accessibility.

  • Close the empathy gap with empathetic design techniques, replacing vague user stories with persona stories that keep development grounded in real user needs.
