Summary

I’m a Senior UX/UI Designer with a business background, specializing in early-stage startups, SaaS and AI products. I thrive as a long-term design partner for startups, joining teams where design is just getting started and bringing structure, scalability and user focus without slowing down the pace of development. I speak the language of tech teams, adapt fast and work hands-on across the full design process.

I'm deeply AI-native: I use tools like Figma Make and Lovable daily to prototype and validate ideas faster, and I bring specialized experience designing AI interfaces, building trust through transparency, confidence levels and the right balance of automation and human control.
