About me
Industrial Design Engineer turned
Senior Product Designer.
Industrial Design Engineering taught me to start with constraints, not aesthetics. Street photography taught me what to include and what to cut. Eight years of complex products later, both still run everything I do.
I work best where the problem space is genuinely ambiguous — consolidating competing platforms, designing permission systems that scale, holding product coherence when the brief is incomplete. That is where structure matters most.
Design philosophy
Most interface problems are architecture problems in disguise.
Research doesn't confirm what I think — it generates questions I hadn't thought to ask.
The hardest design work happens before a screen is drawn.
Now
Sergi consistently demonstrates strong ownership, craft, and judgment on high-impact work. He navigates challenging problem spaces with clarity — grounding decisions in research before converging on scalable, user-centred solutions.
What I bring
I help teams ship products that stay clear, usable, and scalable.
Beyond visual polish, I focus on structure, flow, and decision-making. My work is about reducing friction, supporting real user behaviour, and helping teams move forward with confidence.
The model before the mockup
I start with the underlying data model and information architecture before any interface moves. On RBAC, three competing architectures were explored before the first screen — because that choice determines everything downstream.
Prototypes that create evidence
I use Claude Code to build functional Next.js prototypes when complexity demands it. The RBAC prototype ran real data and real edge cases. Stakeholders gave feedback on actual experience, not speculation about what it might be.
Design as institutional memory
At Corsearch, PM leadership turned over mid-project. I held product coherence across 6 engineering teams by treating context as something to maintain actively — not assume. That is where I was promoted to Senior.
Core skills

Results matter. Leadership
and collaboration make them possible.
Approach
The best outcomes come from clarity, not guesswork.
A clear and flexible process that adapts to each product — combining research, collaboration, and iteration to reduce uncertainty.
