Currently Product Designer in the Financial Services team at Eversports, where I designed the new payments and payouts experience end to end (Stripe integration, payment overview, payout setup) alongside regulatory compliance for France, Germany and Switzerland.
4 years at Monito comparing neobanks and money transfer services, where I designed the iOS and Android app end to end. Revolut user since 2018, so I know the product and its competitors from both sides.
Data-driven: raised conversion through A/B testing at Monito and turned Invia's failing online booking flow into the company's primary sales channel.
Designer who ships: I code (HTML, CSS, JS), prototype with Cursor, Lovable and Claude.

Design of a new product: iOS and Android app
- I designed the app end to end, from user research, ideation, wireframes, and prototyping to custom illustrations and SVG animations.

Digital transformation and conversion optimisation
- I took on a challenging digital transformation online booking project that had a very low success rate (CVR + errors). By improving design, testing, watching session recordings, and communicating with developers, we achieved a success rate similar to that of the call centre, and it is now the primary selling method.
- I designed several successful CVR optimisations for product (hotel detail) pages, including a quick order feature.
