My story
Beyond pixels and prototypes. I design products that solve complex human problems and drive real business growth.
My Journey & Background
I'm a Lead Product Designer with a background in Graphic Design. For over 14 years, I have operated at the intersection of visual craft, product strategy, and digital technology.
Over the years, I've scaled high-impact digital solutions across FinTech, HealthTech, and multi-million user marketplaces. Whether leading design initiatives for platforms like Booksy and Axpo or founding and managing my own studio, my focus stays on the same goal: moving business metrics through clear, resilient product decisions.
As a hands-on lead, I don't just design interfaces—I build them alongside engineering teams. By combining deep UX research with modern AI-assisted workflows (Cursor, Claude), I streamline the path from concept to production without unnecessary overhead.
Areas of ownership
Product strategy and stakeholder alignment
Product vision, roadmaps, and business case definition, partnering with stakeholders and leadership from discovery through go-to-market.
Product discovery and data-driven validation
Qualitative and quantitative research (user interviews, competitive analysis, A/B testing) to de-risk decisions before build.
Design leadership and systems
Leading and mentoring cross-functional design teams, building scalable, accessible (WCAG 2.2) design systems across the full product lifecycle.
AI-augmented delivery
AI woven through research, data analysis, and rapid prototyping (vibe coding with Cursor, Claude, Gemini) to validate and hand off high-fidelity solutions fast.
My daily toolkit
Tools are just a means to an end. I adapt my stack to fit the project's needs, combining strategy, design, and AI-assisted workflows to move fast and solve the right problems.
My product manifesto
Deep user empathy over assumptions
Support tickets and user interviews contain more truth than hours of internal alignment. I design for real human behavior, not idealized personas.
Iterative validation over big reveals
Strategic market benchmarks
Pragmatic AI, not gimmickry
Clarity across every edge case
Simplicity as the main metric
I’ve been lucky enough to work with amazing clients, such as…
Ideas, made real.
Ideas, made real.
