Portrait of Jacqueline Isabelle Klein

I'm Jackie andUser Res is totally my thing.

I'm a UX designer and developer with a particular interest in psychology. I've worked closely with stakeholders for years, which keeps me closely engaged with standards and legal changes, and that's why I factor in accessibility, data protection, and norms from the very start. That way I avoid misguided development, reduce effort, and create potential for innovation.

My Working Method

User Research & Data Analysis

Through user research I see where there's demand or something isn't working, even if I don't yet know why. To understand that, I turn to qualitative methods like contextual observations, interviews, and usability tests, planned partly with Microsoft Forms or Google Forms. I prioritize my findings with frameworks like the MoSCoW method or the Kano model, turning them into clear recommendations.

UX Design & Full-Stack Development

UX design and full-stack development are hardly separate steps for me anymore. I sketch prototypes directly in code with Claude and turn them into reusable components based on the principle of Atomic Design, keeping the whole product consistent. My own portfolio came together that way, built with React and Tailwind CSS and analyzed with PostHog.
