Product & Brand Designer · 20+ years of experience

I design packaging and brands. I build websites and apps.

Cosmetics and FMCG packaging, logos and visual identities, interfaces, websites and web platforms in PHP, and my own apps in the App Store. From first draft to full implementation - for companies directly and as a subcontractor for agencies.

Interface design, SwiftUI code and publishing in the App Store. I do all of it - from the first mock-up to the release.
