Hi, I’m Agnieszka 👋

I'm currently working as Product Designer at Oska Health in Berlin – a digital health platform that raised €11M seed investment. Previously I spent 3.5 years as Lead Designer at Lustery, where I led UI/UX improvements that boosted user retention by 20%.

I work end-to-end across research, UI, and design systems – closely with engineers, PMs, and CPOs in small, fast-moving teams.

What's my work style?

Human-centered

I take time to understand the people I'm designing for – through research, interviews, and simple curiosity about their lives.

Aesthetic-driven

In a world where AI generates endless visuals, I bring the judgment to know what's actually right for the product.

Collaborative

I work best in small teams where design and engineering think together – the closer to the people building it, the better the outcome.

Data-driven

I avoid assumptions by testing early, measuring outcomes, and iterating based on what I learn.

My journey from motion design, through communication and strategy, to product design

Since the beginning of my career, I have freelanced – gaining experience in ownership, self-organization, and process management.

2019 – Transitioned to UI/UX. Workshops for Zalando and APX startups at PEAK. MA in Strategic Design at SRH Berlin (VW, Active Philanthropy)

2020 – Lead Designer at Lustery. 3.5 years, end-to-end ownership, from rebrand and design system to shipped features.

2025 – Product Designer at Oska Health. Prototyping in code, AI workflows, VS Code, Tailwind, and shadcn/ui

When I’m not designing…

You might find me in the darkroom developing analog photos from my travels, solving bouldering problems, reaching a top with rope climbing, or enjoying quiet moments in the sauna.
