Skills
UX Research
From interview scripts and deep listening to usability tests and workshop facilitation. Includes 20+ methods with expanded card sorting analysis, SUS scoring, behavioral audience segments, and Opportunity Solution Trees for continuous discovery.
Design Critique & Evaluation
A 9-step critique framework covering Nielsen's heuristics, 27 UX laws, 50+ interaction patterns, information architecture evaluation, and UX writing review. Specific, not subjective.
Accessibility Audit
Five audit layers — automated, keyboard, screen reader, visual, and flow — against WCAG 2.2 at A, AA, and AAA. Flags issues, rates severity, suggests code fixes, and generates reports.
Journey Mapping
Seven diagram types — journey maps, service blueprints, experience maps, empathy maps, user story maps, and more. Covers service ecology, strategic diagram use, current vs. future state mapping, alignment workshops, and JJG's Visual Vocabulary for flow diagramming.
Design Systems
The full lifecycle — from interface inventory through token architecture, component specs, pattern documentation, and governance. Covers Atomic Design, Kholmatova's pattern approach, and the W3C token format.
UX Strategy
Where design meets business — and responsibility. Opportunity Solution Trees, Jobs to Be Done, competitive analysis, HEART metrics, hypothesis-driven validation, and ethical strategy with shared value creation.
Interaction Design
How things should behave, not just how they look. Microinteraction specs, narrative arc and storymapping, state machines, product postures, motion timing, and a 6-level error prevention hierarchy.
Design Ops & Handoff
The operational side of design work. Five-day design sprints, handoff checklists, critique facilitation, documentation standards, visual QA, and scaled-down methods for solo designers and lean teams.
UX Writing
Clear, concise, user-centered interface copy for digital products. Four quality standards (purposeful, concise, conversational, clear), UX text patterns for every element type, voice and tone frameworks, formatting conventions, accessibility guidelines, and research-backed benchmarks. Originally created by content-designer.
Design Elevation
Transforms functional visual outputs into polished, professional designs. Grounded in Tailwind CSS as the canonical token system, Kholmatova's functional/perceptual patterns framework, and Tufte's data visualization principles. Covers typography, color, spacing, grids, data charts, dashboards, and systematic quality interrogation.
Installation
