About Marcin

I help Enterprise and mid-market SaaS companies build design teams from the ground up or transform fragmented efforts into a single, high-performing organism.


As an Interim Head of UX, I do more than just manage teams. I operationalize them. I bring a battle-tested background in leading 30+ UX specialists across 5 countries (serving 20M+ users), where I successfully unified disconnected local squads into one central, synchronized UX org.

How I can help you:
  • Interim Leadership & Recruiting: I fill the leadership gap to stabilize operations while building your future team. I handle full-cycle recruitment for the entire structure, including UX Designers, UI Designers, User Researchers, and UX Team Leaders, leveraging my daily experience in hiring and scaling diverse teams.
  • Operational Efficiency: I audit and restructure your workflows to move from chaotic output to agile, scalable processes.
  • Strategic Alignment: I translate complex business goals into a clear UX vision and strategy ensuring Design speaks the same language as Product and Sales.

Typical projects I handle:
  • Digital Transformation: Guiding legacy organizations through the shift to modern, user-centered product development.
  • Design System Strategy and Roadmap: Defining the long-term vision and execution plan for your Design System to ensure it actually streamlines development and improves accessibility across all products.
  • Team Unification: Merging silos into a collaborative culture that drives innovation and UX maturity.
  • High-Stakes Validation: Facilitating Design Sprints (enhanced with AI) to de-risk big product bets in days rather than months.
Why work with me?
I combine the strategic oversight of a Head of UX with the hands-on pragmatism of a Product Designer. I leverage AI and automation to speed up discovery and delivery. This ensures your team is not just "doing design" but driving measurable business growth.
