I'm senior product designer with 10+ years of experience on software products and e-commerce platforms. I design the UX from flows and prototypes to polished UI and User test. I write the specs, and work alongside developers through QA until the feature ships.

I'm a senior product designer with 10+ years of experience on complex software and e-commerce products, and I cover the full cycle: research, UX, UI, design systems, and implementation with developers.
UX and UI design: I design user flows, information architecture, prototypes and high-fidelity UI in Figma, for web and mobile. I'm at my best on complex, data-heavy products, like the EPO's worldwide patent search and its internal examiner software, and Auditi's audit platform. I also design AI interactions, such as an AI review tool that shows its confidence and cites its sources, so users can check and override the results.
UX research: I plan and run research myself. At G-Star RAW I worked daily with the CRO team and ran several A/B tests a month. At Sanofi I ran 10 in-depth interviews with pharmaceutical leads to test early prototypes. At the European Patent Office I ran live prototype webinars where hundreds of users validated concepts through polls. I also work with quantitative data: Google Analytics, ContentSquare, sales and returns data, and A/B testing.
Design systems and accessibility: At Auditi I rebuilt the design system. At the EPO I made the application WCAG compliant and improved the component library.
Working with developers, AI-first: I work inside the dev team: I write specs in GitHub, raise my own pull requests for UI fixes with Claude Code, and QA features alongside the developers. I use Claude Code, Claude Design, Claude and ChatGPT every day to explore, prototype and ship faster.
Leadership and collaboration: At G-Star RAW I managed and mentored a team of four designers and directed an external agency. I'm used to aligning many stakeholders: CEOs and CTOs, product owners, marketing and customer service teams. I once presented a product to representatives of 38 European countries.

Project history
Auditi is a SaaS platform used by 500+ audit firms (Grant Thornton, Baker Tilly, RSM, Crowe…) to exchange documents with their clients during financial audits. As a one-person design department, I own product design end to end, from requirements to shipped feature.
- Run research and design flows, wireframes and high-fidelity UI in Figma, with the CEO and CTO as partners.
- Rebuilt the design system: interactive, complete states, and every Figma component matched to the coded one.
- Redesigned the PBC request flow: clients drop files straight into the firm's requests, with comments, citations, file references and mentions.
- Designed AI features like AI tabular review and full-text search, from interaction model to final UI.
- Designed Projects, a new product that grows Auditi into full audit project management.
- Work inside the dev team: daily stand-ups, specs in GitHub, my own PRs for UI fixes, and QA side by side with the developers. Customer support hears it from users: the platform feels more intuitive, even though we now ship many more features.
Led the UX research for Sanofi US's B2B e-commerce platform for vaccine distribution, focused on claims and returns.
- Ran 10 in-depth interviews (about 1.5 hours each) with pharmaceutical leads in France, testing early-stage prototypes.
- Wrote the screener, ran recruitment and kept research goals aligned with the US product team.
- Turned findings into a report with prioritised opportunities and concept directions.
My findings moved the project into the design phase in the US, with decisions backed by real user data.
Led UX for G-Star RAW's e-commerce website and mobile app, with a team of 4 designers and an external agency.
- Ran qualitative and quantitative research: UserTesting.com, surveys, ContentSquare, Google Analytics, sales and returns data.
- Benchmarked 25 competitors and designed flows, prototypes and UI for web and app in Figma.
- Worked daily with the CRO team to run several A/B tests a month, including the PLP fit slider and checkout fields.
- Managed and mentored the designers and interns on the team. We shipped a new Product Detail Page and rebuilt search and checkout. The Jeans Fit Guide, which I designed after linking the most-returned fits to confusing fit names, turned a concept that had failed an A/B test in 2021 into a winning test with higher conversion, and it has been live ever since.
