SENIOR PRODUCT DESIGNER

Hi, I'm Mads

Seeking full-time roles

I design complex digital products and ship fast. I use AI-assisted workflows to go from concept to production-ready UI in hours — and I build the design systems and documentation that keep teams keep moving independently.

Key Skills & Expertise

I cover the full journey — from early ambiguity to shipped product.

Product Strategy


I work alongside PMs to turn messy briefs and competing priorities into a clear direction. Feature scoping, ideation workshops, and roadmap input — I stay involved from the first question, not just when it's time to design.

Design & Prototyping


High-fidelity interfaces, rapid prototyping, and MVP-ready screens. I use AI-assisted workflows to compress timelines without cutting quality — from first concept to tested, handoff-ready designs.

Design Systems


Token architecture, component libraries, and multi-theme strategy. Building the foundations that keep design consistent at scale — and give engineers something they can actually use.

Principles I Stand For

How I show up — to the work, the team, and the problem.

Continuous Learning

Design moves fast. I stay current with tools, workflows, and emerging AI capabilities — not to chase trends, but to bring what's actually useful back to the team.

Solid Foundations

Great products are built on systems, not shortcuts. I invest in documentation, component libraries, and design tokens so the work holds up long after the first ship.

Empowering People

I mentor designers, write handoff documentation that engineers actually read, and share process openly. The goal is a team that doesn't need me as a bottleneck.

Fostering Collaboration

I work across PM, engineering, and leadership — not just handing things off, but staying in the room through decisions. Better outcomes come from fewer silos.

Bias for Action

I'd rather ship something testable than perfect something theoretical. Speed comes from judgment, not cutting corners — and judgment comes from doing the work.

Curiosity & Experimentation

I test assumptions before committing to them. Whether it's a new AI tool, a different component pattern, or an unfamiliar domain — I'd rather explore and be wrong fast than stay safe and slow.
