Look at what actually happens.
I use interviews, support conversations, usage data, and domain knowledge to understand the problem before designing a solution.
Product design for complex software
I make complex software easier to understand and use.
I’m Holger Indervoort, a product designer with a background in technical product management, UX, and data analysis. I have worked with mapping and logistics software since the 1990s. Today I combine user research, product data, Figma, and AI-assisted prototypes to find practical improvements.

The examples are anonymized. The first two include documented artifacts and an explicit account of my contribution. Illustrations use fictional content.
How I work / 03
Understand the real problem.
Make it concrete.
Remove avoidable complexity.
I map the workflow, make trade-offs visible, and focus on the parts that matter most to users and the business.
Build something people can react to.
I use Figma and AI coding tools to make ideas tangible. I specify the behavior, test the result, and refine it with users, product, and engineering.
If a prototype answers the question, another meeting probably will not.
Tools / Actual use
A small toolkit, used for real work.
What matters is not the longest tool list. It is knowing what to use, what to question, and when the result is good enough.
Figma
User flows, interface design, component systems, and detailed interactive prototypes.
Intercom · Productboard
Customer conversations, research evidence, product opportunities, and the decisions that connect them.
ChatGPT · Claude · Codex
I use AI to analyse information, explore solutions, and generate working prototypes. I define the problem, check the logic, and judge the result.
Mapping · routing · logistics
Decades of experience with specialist software, complex workflows, and professional users who do not have time for decorative confusion.
