Working with us

To work with :ratio means to interact with a team of passionate specialists; an experienced and reliable team at your service. We speak French, English, Italian and German.

Simon Farine

Simon

Founder


at :ratio since 2009

“We cannot find anything on this website.” As soon as a client utters these words, Simon is ready to jump into the study and testing of the content and architecture of the site. He maps, sorts, prioritizes, and organizes with an array of acquired experience and methods in information architecture.

Passionate about knowledge sharing, he, along with Gilles, has created the UX Romandie monthly event and the UX Lausanne conference. Always eager to filter new services and paradigms through his analytical sieve, Simon is a key asset to :ratio’s strategic monitoring mandates.

Yann Ringgenberg

Yann

Founder


at :ratio since 2009

Tired of seeing web projects fall slave to fashion dictates in detriment of their specificity, objectives and users needs, Yann founded :ratio along with Simon in 2009. With Yann, navigations, page structures, or interactions do not remain at the level of ideas and words for long; he sketches, prototypes and discusses every aspect of a project, always with the aim of a thorough reworking.

His unfailing taste combined with practical know-how and experience is not limited to user experience; it can also be found in his practice of cycling and music. At work, Yann takes charge of the vinyl collection and the fine-tuning of the record player.

Xavier Alexandre

Xavier

UX architect


at :ratio since 2012

Curiosity is Xavier’s main trait; 3D printing, bicycles (with a preference for light steel), and local culinary products occupy his time. That is, of course, when he is not conducting one of an extensive series of interviews or fine-tuning wireframes.

He dedicates an afternoon per week to widening the scope of his UX vision. For instance, in 2012, he attended an ethno-technology class in Neuchâtel and became an active member of their FabLab.

Our technical partners simply love the fact that he is a certified SCRUM product owner.

Gilles Demarty

Gilles

UX architect


at :ratio since 2013

His previous experience as a developer has served to strengthen Gilles’ main attribute: rigor. Find a user experience difficult to measure? Gilles will quickly prove you wrong through quantitative and statistically based methods.

UX Architect at :ratio during the day, his evenings are dedicated to developing the Interactive Design Professional Association (IXDA) and its famous event: Interaction14. He is also a founder, with Simon, of UX Romandie, a branch of IXDA for the French-speaking region of Switzerland. Despite all these activities, he somehow finds time to tweet and photograph what surrounds and inspires him.

Chiara Valerio

Chiara

UX architect


at :ratio since 2016

No matter what you want to design - be it a product or a service, Chiara’s first question will always be: “who is going to use it?” She uses interviews, surveys, and observational research to understand users' habits and attitudes, then uses that information to build playful and intuitive solutions. Her strengths include empathy, negotiation, and creative problem solving.

Her passion for interaction design comes from a wealth of experience living in Switzerland, United States, the Netherlands, and Italy. If she is not in the field with your team, look towards the sailboats on the lake or on a ski slope! Otherwise, she is probably traveling around the globe.

Matthieu Minguet

Matthieu

UI & Visual designer


at :ratio since 2015

After a Bachelor's program in Interaction Design at ECAL, Matthieu followed a Master's program in Application Development at HEIG-VD. Matthieu has more than one string to his bow; he is passionate about the aesthetics of information as well as the uses and social impacts of new technologies. Matthieu lends us a hand in interaction design and brings his skills to the visual part of our projects.

Besides his job at :ratio, he teaches Motion Design and Creative Programming at ECAL. Hobbies? He is particularly interested in digital artists and finds inspiration visiting expositions both in Switzerland and abroad.

Caroline Altevogt

Caroline

Event Coordinator & Copywriter


at :ratio since 2015

Caroline’s main task is organizing the UX Lausanne conference. After first training in hotel management, she achieved a Bachelor of Arts to satisfy her penchant for linguistics and further develop her way with words. Besides event coordination, she complements the team as a copywriter.

Once her computer is off, she dedicates her free time to entertain her taste buds at the best local restaurants; a hobby that benefits us in choosing the catering for our conferences…

Renato Zülli

Renato

UI & Visual designer


at :ratio since 2018

Whether it is a simple hammer, a connected object or an application, Renato is passionate about tools, their use and their impact. After his training in graphic design at ECAL, he specialized in interface design at EPFL+ECAL LAB.

He likes finding simple solutions to complex problems and rethinking information systems and their visual representation. For Renato, the interface, as a universal tool, is an infinite learning space. But you will also meet him on another field: he trains at the Footbag Net at an international competitive level!

Mélina Fourtune

Mélina

Practical training - 6 months


at :ratio since 2018

Passionate about her studies and eager to become familiar with the professional world, Mélina joined the team of :ratio for a 6-months internship as part of her Bachelor's degree in UX Design at the University of Applied Sciences in The Hague. After she grew up in Africa and spent a few years in the United States, this technology enthusiast now brings an external and new perspective to our projects. She enjoys photography which allows her to be part of the social media team of her university and to feed her Instagram account.
