About.
I'm a Product Designer with 10 years of experience in fintech, crypto, and e-commerce. I design digital finance products that make complex operations feel simple, trustworthy, and intuitive — across web, mobile, and design systems.
I've worked with large companies, fast-growing startups, and freelance clients. That range gives me a practical understanding of how products evolve at different stages — and how to be effective in each context. My focus is clarity, conversion, and user confidence.
I work well in international and cross-functional teams. Distributed collaboration and working across cultures is something I'm used to, not something I adapt to.
Outside of design, I've played music for over 20 years. Creativity has always been part of how I think.
