Senior Product Designer · 10 years · Warsaw, Poland

I solve problems that don't fit into templates

For 10 years I've worked across the full spectrum, from optimising global enterprise platforms to fast-moving startups, equally at home building 0→1 products and evolving mature ones through complex workflow design, large-scale redesigns, new feature development, and scalable design systems.

Core skills

Complexity is my playground

Great products rarely begin with clarity. They begin with competing priorities, edge cases, technical constraints, business goals, and countless opinions. On the surface, it looks like chaos. Underneath, there's usually a simple idea waiting to be revealed. That's the part I enjoy most. I'm equally comfortable moving fast with minimal process or leading structured, cross-functional teams across complex ecosystems, from 0→1 startups to enterprise platforms used globally.

Product Strategy & 0→1 Design

Product discovery, competitive analysis and MVP design, turning ideas into shipped B2B SaaS products fast: concept → prototype → launch, with OKRs and business goals driving every decision.

Product Growth & Optimization

Modernising manual, legacy workflows on products already in use: iterative feature development, automation and smart-matching logic, and roadmap execution that cuts operational overhead.

End-to-End Design at Scale

Leading large-scale redesigns and enterprise platforms used globally: complex workflow and systems design, clear information architecture, and cross-platform execution from Web to POS terminals.

UX Research

User research, usability testing and journey mapping, including compliance-driven UX, with AI-assisted synthesis to remove friction and improve conversion, engagement and task success.

Design Systems & Scalable UI

Component libraries and design tokens for white-label, multi-brand platforms, with iconography, illustration and typography that hold consistent at scale.

Leadership & Impact

Leading and mentoring 10+ designers across remote and hybrid teams, with design governance, hiring, and cross-functional collaboration, aligning design with business goals and measurable outcomes.
