👋 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.
Lately, I’ve been using tools like Lovable, Cursor, and Codex to build interactive prototypes that bridge gaps with engineering, accelerate decision-making and early alignment, and reduce friction by skipping steps in the traditional design cycle. It lets me move faster, stay closer to the work, and contribute at both strategic and practical levels.
I do my best work when collaborating across disciplines, shaping early product direction, 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
- Interactive prototyping with AI
- Breaking down complexity into shippable steps
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 use systems thinking and increasingly AI tools like Cursor and Codex to break them down, prototype ideas early, and explore scalable solutions faster. 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
