Warsaw, Poland · Authorized to work in Poland · International B2B contracts

Businesses have goals.Users have problems.I design solutions that work for both.

I’m a Senior Product Designer with more than 10 years of experience across mobile apps, web products, and VR experiences. I’ve worked with products at different stages — from early concepts and startups to established platforms used by millions — at Vimeo, NerdWallet, AppLovin, and DeoVR.

Animi

Animi is an iOS video editor for creating Instagram stories and reels, TikTok videos, and slideshows using templates, animated text, graphics, and music. The technology behind it made creating and adding new templates quick and straightforward.

    • Designed more than 40 web and mobile products across e-commerce, social platforms, SaaS, digital services, and consumer applications, covering discovery, information architecture, prototyping, UI design, specifications, and implementation support.

I’m a self-taught designer who learned by taking projects from the first client conversation through design and implementation. Working across the full process taught me to navigate unfamiliar problems, take ownership of decisions, and understand how user needs, business priorities, and technical constraints shape a product.

I also have experience launching my own web services and mobile products, with both successes and setbacks along the way. That experience taught me the cost of chasing perfection and shaped how I work: focus on what matters, deliver a considered solution, and keep improving it based on real use. I enjoy finding better ways for products to work — whether that means simplifying an everyday interaction, refining an existing flow, or shaping something new.
