This is how I bank’ is a bold statement: a declaration of the freedom and confidence you get from banking with N26. It challenges an industry that’s increasingly out of sync with what people expect from their bank, and promises that better banking is just a few taps away.

For this campaign, I handled the full transcreation for the French and Spanish markets, developing new scripts and fresh lines while keeping the core message and tone consistent across regions. I also adapted the main tagline to ensure it felt natural, modern, and culturally spot-on in both markets.

At R/GA Berlin, we were tasked with launching Google’s video game service, Stadia, across three key European markets: France, Germany, and Spain. We set out to reimagine what it means to be a gamer: no console, no downloads, no updates. Just you, your screen, and instant access to top-tier games at the push of a button.

Beyond the core campaign idea, I re-wrote and adapted the scripts for the French market, ensuring the VO lip-sync matched naturally with the English master to keep everything seamless on screen. I also handled VO casting and direction. Beyond the hero films, I contributed to the creation of additional assets such as social content, banners, and OOH.

Plum automates your saving. The customer research showed that people know they could be saving better, and why that’s important, but just don’t get round to it. So instead of focusing on product, we spoke to the root causes of financial inertia, positioning Plum as the answer to procrastination and the fear of getting it wrong.

With this insight as a springboard, I crafted the new French lines, shaping the rhythm, rhymes, and punchlines to land smoothly and memorably for the audience. These adapted lines became the backbone of the OOH campaign in France.

Using the US Slack's current creative concept: 'It wouldn't be email at all,' developed by R/GA San Francisco, we were asked to come up with new copies and add cultural elements that alluded to the mainstream corporate culture in each market (France, UK, and Germany). This allowed the new audiences to resonate with the concept in a much more accurate way.

Apart from online videos, the campaign included social media (IG, FB & LinkedIn), TVC, OOH, and banners.

To support the launch of the release of the final season of La Casa De Papel in France, Netflix launched a nationwide campaign to find the show's biggest fan. Amplify created a format-busting IRL-meets-content fully integrated phased campaign that mobilised Money Heist's devoted fan base, to find and reward the ultimate fans of the series in France and Poland.

With this campaign (online video, social media, microsite...) we wanted people across France to realise the incredible fandom that surrounds the show and the impact it's had on pop culture.

What if modern work wasn't slowed down by a lack of effort, but by invisible habits instead?

The Ping-Pong Effect turns one of the most common workplace frustrations into a playful metaphor: a task that keeps bouncing from one colleague to another, while progress quietly stands still.

Developed as a speculative campaign for Notion in 2026, the film imagines "Work Without Side Effects" as a platform built around the everyday dysfunctions of modern work. Created entirely with AI-assisted workflows, the project explores how generative tools can accelerate the journey from script to final execution while preserving creative direction, storytelling and craft at every stage.

Football is a game played with the feet. And lived through the hands.

Hands clapping. Hands praying. Hands trembling. Hands gripping. Hands covering eyes.

"A Handful of Passion" builds on that simple observation, turning the emotional language of football fans into a tangible brand gesture: harvest by hand the potatoes and reaching for a Lay’s crisp.

Developed as a speculative project in March 2026, the film also explores emerging AI-driven workflows, testing how generative tools can help reduce the gap between concept and execution while keeping creative direction at the center of the process.

Transcreation goes beyond translation: it's about capturing the cultural nuances of the target region and tailoring the message to resonate with a new audience, all while preserving the original brand's tone of voice.

A selection of OOH work for different brands, from contextual executions in train stations and the Paris Métro to destination-led campaigns.

For SumUp France, I worked on the French adaptation of “Get Out Here”, developing the messaging and OOH executions for the French market, including the tagline.

For Trainline, a bespoke billboard at Gare de Lyon echoed the destinations displayed on the departure board beneath it.

For Nature’s Variety, we turned everyday Parisian train annoyances into humorous headlines around the idea of being “easier to digest.” (Agency: Dude London / CD: Hamish / Copywriter: Julien Marsouin)
For Vueling Airlines, we personified European destinations through playful relationships: flirting with Copenhagen, having a match with Paris, or an affair with London.

Four tribes, living worlds apart, bound by the same instinct and way of life: to run. From the mountains of Mexico to the plains of Southern Africa, this film takes us on a journey through time and across continents to explore how running has shaped, and continues to shape, their lives.

But beyond their stories, it’s an invitation to reflect on our own need for movement, and the primal drive that keeps us moving forward.

As human beings, we’re constantly doubting in our everyday lives. Green or blue shirt for an important call? Italian or sushi for a first date? Clifford or Cooper for the puppy’s name? Life is already complicated enough... which is why idealo exists: to help people easily compare and find the best option among millions.

I developed the creative concept built around this insight, then wrote the scripts, selected and directed the French voice-over, and provided cultural guidance to make sure the campaign resonated naturally with the local market.
