Hello 
I’m Oliwier, a Product Designer with 5 years+ of experience with a background in graphic design and motion design.
I have designed products for companies such as Billin.app, T5M Ekipa, Rewardo.app, Warsaw University and Port Sopot and many others.
I have experience in mobile app design, web app design and design systems. I’ve collaborated closely with several companies to help them structure their own component libraries and enhance their design operations.
What projects have I participated in?
Aplication to reviews
Billin is a social application for posting reviews not only about companies, but also about events, movies, food - literally everything. The app, combined with gamification elements, motivates users to publish content.
Business Panel
This tool, integrated with a mobile app for posting reviews, enables companies to manage profiles, publish content, analyze statistics, and create marketing campaigns similar to Meta Ads or Google Ads. Thanks to its simple and modern interface, businesses can effectively control their image, reach their target audience, and measure the effectiveness of their activities.
Marketing application
The application was designed in collaboration with “Ekipa Holding S.A.” (the largest group of influencers in Poland) as part of the “Your 5 Minutes” program, serving primarily as a voting tool, but not only that. It played a key role during the show’s. The app successfully motivated users to engage with the platform and keep watching the program.
Financial App
A financial application in which the mobile component is focused on the speed of performing key operations - such as payments, balance overview, and card management - while the web version extends these capabilities with deeper analytics, advanced settings, and comprehensive management of financial products. The entire system is based on a unified design and a modular interface, enabling smooth navigation and personalization.
Dedicated Loyalty Apps
Loyalty applications that help small businesses increase the effectiveness of selling their products and services. The applications are equipped with an intelligent loyalty system that motivates customers to engage with the companies’ offerings.
Design system for projects
A comprehensive design system that has become the foundation for all digital products created within the organization. A consistent visual language and standardized interface components that enable fast and scalable development of new features without compromising the quality of the user experience.
