I help product organizations fix interface delivery breakdowns.

Why product delivery becomes unpredictable.

Planned work doesn’t ship on time

Sprint goals slip because UI decisions keep changing. PMs renegotiate scope and deadlines every cycle.

Small interface changes feel risky and slow

Patterns aren’t trusted. Teams hesitate, rework increases, and velocity drops as products scale.

AI multiplies inconsistency

AI speeds up output, but increases cleanup and rework because structure and semantics are missing.

These are interface problems, not design problems.

How I help teams regain delivery reliability.

I start by making interface decisions explicit. Only then do structure, tools, or execution make sense.

Done with you

  • Diagnose interface delivery bottlenecks
  • Map where decisions break down
  • Align product, design, and engineering
  • Define interface structure and governance

Done for you

  • Implement a focused slice
  • Codify patterns or components
  • Unblock delivery fast

Execution is a mode, not a service.

Most engagements start “done with you”. Execution is used only when it removes friction.

Tools & artifacts

These are working tools I use to diagnose and discuss interface delivery problems.

Interface delivery maturity check

A lightweight way to assess delivery reliability and structural gaps without jargon.

Interface delivery bottleneck map

A guided self-diagnosis to surface where interface decisions break down across teams.

Notes / essays

Short pieces where I think through recurring patterns, failures, and trade-offs I see in product organizations.

All tools are designed to be used in conversation, not consumed passively.

In practice

Matthias’ questions drilled deep and always with purpose. He turned a draft into an actionable design system. His structured approach gave us the clarity we needed to move forward with confidence.

We had hit the point where scaling design without a system just wasn’t working anymore. When we decided to build a design system, Matthias was the first person I thought of. He didn’t just help us structure components. He helped us align on strategy, adoption, and long-term maintainability.

Portrait of Matthi Dunker

I work at the intersection of product and interface delivery. My work focuses on systemizing and evolving interface delivery across design and code inside real product organizations. I’ve coached design chapters and worked closely with product and engineering leaders on alignment, governance, and delivery reliability. I’m often brought in when teams are shipping, but delivery feels unpredictable. And when structure, not effort, is the missing piece.


If this resonates, the best next step is a short conversation.

Let’s have a focused look at where interface delivery is breaking down.
