Daria Fefelova — Mobile UI/UX Designer
I create intuitive and visually engaging mobile interfaces that help people connect, share experiences, and solve everyday problems. My work combines user-centered thinking, clear interaction design, and a visual approach tailored to each product’s audience

Every mobile product has its own audience, context, and set of challenges. Designing for these differences requires more than applying the same interface patterns.
Through four projects, I explore different aspects of mobile product design: simplifying complex interactions, creating navigation systems, encouraging social engagement, and prioritizing essential features

PARU
Making skill exchange accessible
People often have skills they would like to share and others they want to learn. However, finding a suitable exchange partner and organizing the learning process can be challenging.
Paru is a mobile application designed around the idea of exchanging knowledge and skills without traditional payments.
The design challenge was to create an experience where users could easily discover relevant skills, find compatible partners, and understand how the exchange works
The main focus of the project was to make the skill exchange process understandable from the very first interaction.
The experience is organized around several key actions: discovering available skills, exploring user profiles, finding an exchange partner, and managing the learning process.
Particular attention was given to how information is presented and how users move between these stages without feeling overwhelmed
This project demonstrates my ability to organize complex product mechanics into clear and intuitive user flows
SK8X
For skaters, urban spaces are more than streets, stairs, and squares. They are potential spots, places to practice, and meeting points for the community. Yet discovering suitable locations, keeping track of personal progress, and connecting with other skaters involve different activities. SK8X brings these parts of skateboarding culture into one digital environment.
The ambition was to create something that feels genuinely connected to the skateboarding lifestyle, rather than simply adding skate-related visuals to a conventional application
Rather than relying on a neutral visual style, SK8X embraces the personality of its audience. Expressive graphics and a distinctive interface language help create a recognizable product identity. At the same time, navigation and information hierarchy remain essential. Users should be able to discover skate spots, explore community features, and follow their progress without unnecessary complexity.
The project brings together mobile UX, location-based functionality, and visual communication within one coherent experience
LIBBADDI
Reading can be a solitary experience, especially when there’s no one to share thoughts, emotions, or discoveries with. Without a sense of connection or shared purpose, even passionate readers can gradually lose motivation.
Finding someone who enjoys similar books is one thing. Finding a person who shares your interests, reading goals, and desire for meaningful conversation is much harder
Instead of building another platform focused primarily on books, Libbaddi puts people at the center of the experience.
The service connects readers based on their literary tastes, personal interests, and reading goals. By matching users with compatible companions, it creates opportunities for meaningful discussions, mutual encouragement, and shared reading experiences.
The design focuses on making these connections feel natural, turning an individual hobby into a way to meet like-minded people and maintain motivation
The result is a concept that goes beyond book discussions, using shared interests to foster connection and a sense of belonging
