Product Design
I design websites and digital products end to end, from wireframe to pre-launch QA, together with the development team.

Approach
I design user-centered digital experiences, applying methods and principles that ensure intuitive, functional interfaces.
My goal is for every design to be clear for people, feasible for the dev team and aligned with business needs.

What I do
- I design complete websites from wireframe to production: I delivered 3 sites end to end, several of them led on my own.

- I created 2 custom icon systems that are still in use across the company's and its clients' products.
- I defined Google Business Profile design systems applied to 3 client accounts, unifying their visual identity.
- I run design QA with the development team before every launch to ensure fidelity between the design and the live site.
- I join client meetings with the PM and coordinate tasks with the design team.
