My Services

Design partner

I join as your designer and handle the design from the first sketches to launch, working directly with your developers.

First step

A call about your product and what matters most right now.

Audit and design system

I find what's making the product hard to use and what to fix first. Then I build a design system that keeps it consistent as you grow.

First step

An audit, a fixed-scope project, so you know exactly what you'll get.

Working prototype

I design the idea and build a working version with real data, so you can test it with users or investors before you commit to development.

First step

Agreeing on what the prototype needs to prove.

Extra capacity

I join your team for a project or a busy period, using your tools and your process. White-label is fine.

First step

A look at the brief and your timeline.

Selected Work

Recent work. Full case studies, including the retail analytics project, available on request.

Multinational Retail Company

X Redbility

2021–2026

Turning scattered data into daily decisions for distribution teams.

Analysts made daily decisions by piecing together data from four separate sources. I mapped their journeys, identified the flows that mattered most, and designed dashboards that adapt to their changing goals across the week.

I was the only designer on the project, working with business teams and 50+ developers across 5+ internal tools.

  • Time spent on weekly review

    −25%

  • Replaced 4 or more Excel files with 1 dashboard

Fitness Startup

2023–2025

From UX audit to a redesigned app and a design system for iOS and web.

1FIT is a fitness startup with a B2B2C model, which lets fitness coaches give their clients an app to track their progress.

I started with a UX audit of the iOS app: its main action, logging daily data, was buried two or three levels deep, and the app had no clear primary goal.

As lead designer, I redesigned the client app around daily logging and coach feedback, built a custom design system for iOS, and tailored IBM’s Carbon to the coaches’ web app, migrating the existing screens onto it.

Workout Logger

Side project · 2026

A workout tracker built around muscles, not routines

Most fitness apps assume you follow a fixed plan. I designed Workout Logger for people who train what they feel like: pick a muscle group, tap to log a set, done. It tracks weekly sets per muscle and suggests what to train today based on recovery.

I built it with Claude Code on Supabase and Vercel: a live product with accounts, real data, offline support, in English and Italian. It’s the same way I build working prototypes for clients.
