Experience
My interest in digital world naturally led me into design. I've continually refined my skills—from sketching wireframes on paper to mastering graphic tools. Throughout my career, I've gained valuable insights into the business and client sides of design. As my expertise grew, I shifted toward a broader scope of product/service design, where I emphasize creating user-centered experiences across online and offline touchpoints. I aim to design solutions that are not only pretty but also intuitive, accessible and joyful. I strive to push boundaries by blending creativity with strategic thinking. I like discovering the unknown, thinking big, working fast and focusing on positive impact.
Highlights:
– Was the UX designer for a streaming platform for Hungary's top stand-up comedy group
– Designed a gamified web app which had 20,000 users in 2 months, completing 62,000 challenges
– Created an AI-powered food delivery mobile application that compiles orders based on taste
– Delivered a modernized and well-structured ERP, improving process speed by ~40% and reducing errors
