Senior Product Designer — 11 years in B2B SaaS & ERP.

Here are some examples of how I combine research, prototyping and a product mindset to design B2B software.

Shu‑Min Yang

Eleven years of making enterprise software feel simple.

I spent six of those years at Sage, designing ERP workflows — time tracking, procurement, shop-floor execution — the kind of software where a confusing screen costs real money. I ran field research with operators and buyers, facilitated design sprints with leadership, led UAT, and contributed patterns back to the design system across product lines.

Then I rebuilt my workflow around AI. I still start with research, but I now design in code with Claude — so what I hand over isn't a mockup, it's working software: real data, real states, ready to test. That shift is what let me explore agent transparency patterns, human-in-the-loop controls, and ship a full SaaS product solo. 20+ prototypes and tools so far.

  • 11 years in B2B SaaS — 6 at Sage on enterprise ERP (X3, Operations)
  • Research-led — Field studies, design sprints, UAT with real operators
  • Design systems — Components and patterns adopted across product lines
  • AI-native workflow — Prototypes are working software, built with Claude in days

Open to senior product design roles (Paris · remote EU) and select freelance engagements.

Together, let's put your ideas to work
