Hi, I'm Derek Stein!
UX researcher and designer turning friction into clarity, backed by psychology.
Atmosfy
Identified and resolved social friction patterns across a multi-million user discovery platform, leading 84+ moderated sessions over 7 months that drove shipped design changes to onboarding, engagement, and retention flows.
Intersight AI
Led discovery research for an AI communication coaching concept in healthcare, rebuilding the question bank, moderating stakeholder interviews, and identifying adoption barriers that shaped product positioning.
Belle D'Amour
Redesigned the end-to-end shopping experience for a women's fashion brand, rethinking collection browsing, product pages, filtering, and navigation to improve discoverability and conversion.
Tesla Control Center
Researched the transition from physical controls to touchscreen UI across 48 Tesla owners, identifying safety-critical pain points and designing a data-backed interface improvement.
Psychology-trained UX researcher and designer. I turn user behavior into product decisions.
I’m a UX researcher and designer with a master's degree in psychology, focused on understanding how people actually behave and turning that into better product decisions.
I got into UX through studying human behavior and applying it to real product work. Since then, I’ve run 80+ moderated usability sessions, identified recurring behavioral patterns, and translated those insights into changes to onboarding, engagement, and core product flows.
I work across both research and design, from defining problems and running studies to designing solutions based on what users actually do, not what we assume.
What I Bring
Research that drives product decisions
I don’t hand off reports and walk away. Findings are structured so teams can act on them immediately, shaping what gets built next.
Behavior → design translation
I turn observed user behavior into clear product changes. Patterns don’t just get documented, they get designed into better experiences.
From insight to interface
From writing a screener to designing the solution. I run the study, synthesize the findings, and create what comes next.
