Team energy
I like open feedback loops, design critiques, and sprint rhythm where everyone can see the product getting clearer.

About
I build product interfaces that feel polished, usable, and ready for real teams.
I am Olzhas Kabi, a UI/UX Product Designer based in Warsaw with 5+ years across iOS, Android, and web products. My work covers discovery, user research, information architecture, wireframes, high-fidelity UI, interactive prototypes, and developer handoff.
I care about systems as much as screens: design tokens, component governance, Apple HIG, Material Design 3, and Figma Dev Mode specs that reduce back-and-forth with engineering. I also use AI tools for fast visual exploration and concept art direction when the product needs range quickly.

Profile
Designer who likes people, product logic, and fast-moving teams.
I enjoy working in collaborative environments, discussing ideas openly, and turning team feedback into sharper user flows. I am comfortable between product, design, engineering, and business conversations.
Education
Computer Engineering foundation
Vistula University and WSIiZ Rzeszow.
Outside work
Basketball, travel, conversations
I like staying active, meeting people, exploring new places, and bringing that curiosity back into design work.
How I work
Design is sharper when the room is moving together.
My strongest work usually happens when research, design critique, engineering detail, and real conversation stay close to each other.
Technical base
Computer Engineering studies help me speak with developers and think about feasibility early.
Motion mindset
I use motion to explain hierarchy, state changes, and the feeling of a product, not just to decorate it.
World input
Travel, basketball, and everyday conversations keep my eye tuned to people, behavior, and visual culture.
Experience
Mobile-first product design with system-level thinking.
I have worked across startups, production platforms, international Agile teams, and design-heavy product environments. The common thread is simple: turn messy product input into clear flows, scalable UI, and clean handoff.
