Complex systems, simple outcomes.

Senior UX & Service Designer for regulated, multi stakeholder platforms. I help teams ship improvements that reduce user effort and support demand—measured in NPS/CSAT/CES (CX Metrics), adoption, and accessibility.

I bridge the gap between user empathy and business rigor.

From mental models to policy rules: I make complexity navigable, traceable, and measurable—without breaking compliance or operations.

Quick Facts

Location: Netherlands (Utrecht area) • Remote/hybrid possible (role-dependent)

Focus: ux design • ux research • journey ops • service blueprinting • IA/terminology • AI ready interfaces • accessibility

Collaboration: workshops • alignment with stakeholders • governance/DesignOps

Domains: insurance/healthcare/public/telecom/retail • enterprise portals • international programs

Tools: Figma • TheyDo • Miro/FigJam • GA/Clarity/PowerBI • WCAG • Jira

Signature method

1) Diagnose

Evidence scan (metrics + support signals + heuristics) to define the real constraint and success metric.

2) Map the system

Journey + service blueprint to connect user intent to backstage rules, teams, and handoffs.

3) Prototype & test

Rapid prototypes to reduce uncertainty (navigation, terminology, scanability) before build.

4) Land & scale

Implementation handover + governance/DesignOps + measurement so the change sticks across teams.

Selected work

Each example is written NDA-safe: problem, my role, outcomes, and key decisions.

Problem: Desk/competitive research was slow to triage and hard to keep evidence traceable.

Role: UX lead for the workflow (prompt structure, output template, quality checks).

Outcome: Faster, more consistent research synthesis with clearer evidence trails (augmentation, not replacement).

Constraint / decision: Reliability risk → enforce structure + sources + spot checks.

UX • AI/agents • Research ops • Microsoft Copilot

Problem: High user effort in a regulated healthcare authorization journey with handoff friction.

Role: Service/UX lead (journey management, blueprinting, conversational patterns, governance).

Outcome: Measurable effort reduction and improved experience (+8 NPS-d).

Constraint / decision: Multi-stakeholder process → blueprint backstage before UI patterns.

Healthcare • Journey ops • Service blueprint • Conversational patterns

Problem: Insurer-driven structure and terminology caused cognitive mismatch (NPS-d −56).

Role: Lead UX/Service Designer + AI concept track (IA, terminology, prototyping, validation, alignment).

Outcome: NPS-d improved from −56 to +7 within 3 months, with reduced customer contact and an AI-ready structure.

Constraint / decision: AI trust varies → dual-mode interaction (click paths + AI support), not AI-only.

Healthcare • UX redesign • IA/terminology • Accessibility • AI-ready search
