Senior UX Researcher: mixed-methods research for complex digital products
Pegah Redjai Sani
Senior UX Researcher
Hi, I'm Pegah an experienced UX Researcher with a strong background in UX design, graphic design, and photography. My work is driven by a deep understanding of human psychology and user behavior, allowing me to uncover insights that shape intuitive, user-centered experiences.
I specialize in survey, usability testing, user research methodologies, heatmaps, wireframing, and prototyping, ensuring that design decisions are backed by meaningful data.
Passionate about bridging the gap between user needs and design solutions,
I collaborate with cross-functional teams to enhance usability and deliver impactful, research-driven designs.
Further strengthening my expertise, I completed Human Mind, Practical AI,
One-Person UX, Storytelling and UX Leadership courses at Nielsen Norman Group (NN/g), focusing on advanced UX research methodologies.
I'm based in Rotterdam and looking for a research role where I can work closely with product, design and engineering on products that are hard to understand, and help the team make better decisions.
Improving STRATO’s Website Navigation
(STRATO is an internet hosting service provider based in Berlin, Germany.https://www.strato.de/)
Our website used top navigation, and desk research suggested side navigation might work better. Since navigation is one of the most critical parts of a website, I wanted to be sure before we asked designers and developers to change it.
I started with card sorting to check whether people understood our categories. Then I compared top, side and hybrid navigation in usability tests.
Users liked side navigation more than they expected, but it ran into a real limit with our showroom pages.

Price Communication At Strato website
(STRATO is an internet hosting service provider based in Berlin, Germany.https://www.strato.de/)
This project explored how competitors in the German market communicate free-trial offers through pricing displays in showroom environments. The research focused on understanding competitive pricing strategies, how free-trial messaging influences customer perception and behavior, and which approaches create greater clarity and appeal.
The findings were translated into actionable design recommendations, helping inform pricing-display decisions and improve the overall customer experience.

Accessibility in the backlog: how research turned into action
Accessibility was new territory for our team, and Lighthouse showed we had work to do. But a report alone doesn’t change a website, so I wanted a way to get designers, developers and the product owner working on it together.
I started with research, using Figma’s contrast checker and Lighthouse to see where we stood, then presented it to all three groups. Next, we set up a two-weekly meeting where each finding became a Jira task, with the research and the needed change attached.
Step by step, the team improved the website and worked toward WCAG AA, which we reached.

UX / UI challenge : From Research to design
Several years ago, I tackled three key research design challenges, exploring various research methods and design approaches. While these case studies are not recent, they represent a significant milestone in my growth as a UX researcher. At the time, I was refining my expertise in user research, and these projects laid the foundation for my professional practice today.
These case studies, originally documented in articles on Medium, showcase how I applied surveys, competitor analysis, user interviews, and desk research to uncover actionable insights. Each study highlights the role of research in shaping design.
