What I'm looking for

I'm seeking opportunities in UX/UI Design, Product Design, and AI Design Evaluation.

At Chit Chat AI, I designed the web product end-to-end, from the landing page and character catalog to responsive chat and account flows. I also designed the in-app economy, including character banners, drop-rate logic, and virtual-currency systems.

At Jagiellonian University Computer Science Student Association (KSI UJ), I designed posters and social graphics for student events and the association’s T-shirt. I’ve also evaluated Grok’s mathematical reasoning for Mercor’s contract project for xAI, and worked on Qt-based POS and self-checkout interfaces at CHM Software.
