behavioural ux, upstream of every tool that builds

Staff product designer. I diagnose why behaviour stalls and fix it end-to-end, from research through shipped product. Behavioural lens, measured outcomes, design systems that compound after I leave. Currently building Nudgent, a behavioural-scoring SaaS in early access.

Based in Barcelona, working globally.

Nudgent. A behavioural substrate beneath the LLM.

The behavioural lens behind every case above, now a self-improving engine. Built solo, end to end. A specialist for any industry, surface, and stage, drawing on seventy years of peer-reviewed research, scored against any page in five minutes. Compounds with every analysis run, every paper added, every model release that follows.

1972
Cognitive dissonance theory
Festinger
Behaviour realigns with attitude when both are visibly tied. Used to weight commitment cues on confirmation screens.
1979
Loss aversion
Kahneman & Tversky
Losses weigh roughly twice as much as equivalent gains. Surfaces wherever copy frames an outcome to avoid versus an outcome to pursue.
1984
Social proof
Cialdini
People follow the visible behaviour of others, weighted by perceived similarity. Scored on testimonials, counts, and named adopters.
1993
Peak-end rule
Kahneman, Fredrickson, Schreiber, Redelmeier
Memory of an experience is dominated by its peak intensity and its ending. Drives weighting on confirmation, error, and exit moments.
2003
Default effect
Johnson & Goldstein
Pre-selected options are taken at vastly higher rates. Audited on every form, settings panel, and consent surface.
2006
Endowed progress effect
Nunes & Drèze
Pre-existing progress raises the rate of completion of the same task. Surfaces wherever a multi-step flow is presented.
2008
Choice architecture
Thaler & Sunstein
The structure of how options are presented changes which is chosen, without removing any. Frames the audit's weighting on layout decisions.
2011
Goal gradient effect
Kivetz, Urminsky, Zheng
Effort accelerates as the perceived end approaches. Audited on progress indicators, completion rings, and step counters.
2015
Labour illusion
Buell & Norton
Visible work raises trust and perceived value. Drives weighting on loading states and reasoning surfaces.
…
Three hundred and counting
Indexed by industry, surface, and stage
Each one named, weighted, and scored. The substrate compounds with every paper added and every model release.
