š Hi, Iām Jeroen
Product designer with a knack for developer tools, collaboration workflows, and making complex systems feel simple.
I help teams turn ambiguity into direction by breaking down big ideas into practical steps they can act on. My strength is systems thinking: spotting patterns, mapping workflows, and shaping experiences that work across messy, interconnected contexts. I keep teams aligned, grounded in real user needs, and moving forward with intent.
Recently, I have been using tools like Cursor, Lovable, and ChatGPT to prototype fast, test ideas earlier, and bridge gaps with engineering. AI-powered prototyping helps me explore multiple solutions quickly, accelerate decision-making, and reduce friction by skipping unnecessary steps in the traditional design cycle.
I do my best work with cross-functional teams. I help shape early product direction, navigate complexity, and fine-tune the details that make an experience feel right.
I am curious by nature, stubborn in the best way, and an occasional wise-ass. 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 am a DIY-er, sim racing rookie, and metalhead. I am driven by impact, allergic to BS, and happiest when I am building something that actually works. Whether it is a feature, a wall, or a playlist.
Experience
Postman
2022 – present
(Sr) Product Designer
I design collaboration tools for more than 35 million developers using Postman. My focus is on making it easier for teams to share, comment on, and build APIs together by turning fragmented workflows into seamless, intuitive experiences.
The problems we work on are deeply interconnected, so 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 work closely with engineering, PMs, and 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 improve discoverability and ease of use, growing weekly comments from about 750 to more than 7,000
- Contributed to a 24% year-over-year increase in collaborative users on paid plans

Product Designer, UX/UI
I was the sole designer at i3D.net, leading end-to-end design across products and platforms used by game publishers and developers worldwide. My focus was creating scalable, intuitive experiences for managing high-performance game infrastructure.
I partnered closely with product, engineering, and commercial teams to simplify complex systems and workflows, applying systems thinking to design tools that support always-on, multiplayer environments.
Key outcomes:
- Designed and launched a responsive UI platform used to manage infrastructure for more than 250 million players
- Built and maintained a design system to ensure consistency across the platform
- Redesigned corporate websites, improving lead quality and conversion rates
- Helped design tools and workflows that supported the launch of AAA games such as The Division, Rocket League, Skull and Bones, and platforms like Discord
I also supported branding, marketing, and QA to ensure a consistent experience across all touchpoints.
