Hi, I’m a Product Designer passionate about creating user-friendly experiences. I love front-end, which helps think creatively aware of technical constraints.

With 10+ years of experience, from startups to global teams, B2C to SaaS, I’m now looking for a new opportunity to contribute and grow.

I love working with other designers, bouncing ideas around, sharing quick feedback to building great interfaces together. I believe open communication drives better design.

I’m not an engineer, but I’m highly technical and speak the same language. I design with front-end in mind to deliver clear specs - Always happy to jump in and help with front-end.
