Looking for UI prototypes to create a non-commercial UX sound portfolio

Hi everyone,

I’m Pablo, a sound designer transitioning into UX / Product Design, with a focus on UI Sound and Product Sound Design.

I’m currently building a non-commercial portfolio and I’m looking for UI prototypes, interaction flows or motion concepts that I could use with permission to design sound feedback (micro-interactions, confirmations, errors, transitions, etc.).

The visuals would always remain fully credited to the original designer, and the work would be clearly presented as an unofficial sound redesign for portfolio purposes only.

If you have a prototype (mobile-first, SaaS, fintech, health, etc.) that you’d be open to sharing for this kind of collaboration, or if you know where designers usually publish such material, I’d really appreciate your guidance.

Thanks in advance, and happy to connect.
