Stefan Zwegers

Prototyping Design Thinking Product Strategy Hardware + Software User Research Agile / Scrum AI-assisted prototyping

I love the moment when a duct-taped prototype actually works. Then my brain kicks in: how does this survive the real world?

15+ years bridging the gap between wild ideas and reality. I've helped build glowing roads, lightweight solar panels, and education platforms used by 172.000 people daily.

I ask questions others don't. I translate between engineers, designers, and management so everyone actually understands what they are building. And I'm not afraid to pick up a soldering iron or be out there in the rain myself.

I work best with teams who trust their people and want to build things that matter.

Through user research, technical testing and analysis.

03

Product Leadership

Products delivered on time with roadmaps everyone understands.

Creating a team that knows it's strengths and weakenesses and how to leverage them to get results.

05 — AI-ASSISTED PROTOTYPING

Same loop,
stronger tools.

AI doesn't change what I build or why. It changes how fast I get there and how much of the execution I can handle myself. I still own every architectural decision, every design choice, every validation.

SPEED

Concept to PoC in days

Prototypes that used to take weeks now take days. More iterations per sprint, earlier answers on whether an idea actually works.

SKILLS

More disciplines, independently

ML pipelines, front-end builds, security hardening, test suites: disciplines I would have outsourced before. Now I execute them myself, with AI as a skilled execution partner.

STRUCTURE

Not random, directed

Spec-first, documented decisions, CI hooks, test coverage. Every step reviewable, reversable and controllable. I think that is the difference between directed AI development and vibe coding.
