👋 Hi, I’m Jeroen
Product designer with a knack for developer tools, collaboration workflows, and making complex systems feel simple.
I help bring focus to unclear problems by turning big ideas into practical steps that teams can actually move on. I’m especially strong in systems thinking: spotting patterns, connecting dots, and shaping experiences that work across contexts. I help teams find direction, make steady progress, and stay grounded in what users actually need.
I do my best work when collaborating across disciplines, shaping the early direction of a project or feature, and fine-tuning the details that make an experience feel right.
Curious by nature, stubborn in a good way, and a professional wise-ass by trade. I learn by doing, whether that means rethinking a workflow or figuring out how to tile a bathroom with YouTube.
Core strengths:
- Developer experience
- Collaboration workflows
- Product strategy and shaping
- UX quality and simplification
- Cross-functional EPD thinking
- Breaking down complexity into shippable steps
Â
Outside of work, I’m a DIY-er, sim racing rookie, and metalhead. I’m driven by impact, allergic to BS, and happiest when I’m building something that actually works, whether it’s a feature, a wall, or a banging playlist.

Experience
Postman
2022 – present
(Sr) Product Designer
I design collaboration tools for over 35 million developers using Postman. My focus is on making it easier for teams to share, comment on, and build APIs together—turning what can be a fragmented experience into something more seamless, intuitive, and workflow-driven.
The problems we work on are often complex and interconnected. I rely on systems thinking to break them down, connect user and product needs, and design solutions that scale. I collaborate closely with engineers, PMs, and fellow designers across time zones to uncover pain points, simplify workflows, and remove friction from everyday teamwork.
As a senior IC, I also mentor junior designers, helping them grow their craft, navigate complexity, and build confidence in their design decisions.
Key outcomes:
- Increased share flow conversion from 8% to 28% through UX-led improvements
- Redesigned commenting to drive discoverability and ease of use, growing weekly comments from ~750 to 7,000+
- Contributed to a 24% year-over-year increase in collaborative users on paid plans
