"How to create a more readable and understandable interface while maintaining the current DA"

"How to help a multiplayer project without any pre-existing interface"
Jumpers is a small, independent project with a well-developed and existing gameplay loop, but no interface had been created. It was necessary to go back to the user interview stage to identify areas for improvement and key points to address. There was also a significant amount of work involved in creating illustrations.

"I had the opportunity to work with Sacha on a video game project carried by an entirely female team. Sacha took care of the entire UI and UX of the game: from the creation of the interface through the player experience to the integration of assets into the engine, on Unreal Engine 5. His rigor, his ease in creating group cohesion and his ability to listen are all complementary assets to his technical mastery and deep knowledge of art and the world of video games. Sacha knows how to offer precise, innovative work and at the service of the player. I highly recommend you to collaborate with Sacha: she will enrich your project by her creative spirit, her seriousness and her unique imprint."

"Thorough and to the point, Sacha took to her assignments with remarkable speed and autonomy. During our all-too-short collaboration, she was able to navigate a complex technical environment, bringing creativity and rigor to bear. As a junior UX UI designer, she provided perfect support for our designer and helped our developers to follow through on projects. In charge of communications, the creative touch of her designs not only met our expectations, but also strengthened our brand image. Finally, her energy, dynamism and leadership skills have been invaluable assets in our 100% remote organization."
