Martina Mitz
UX Designer and Psychologist
Martina started as a self-taught Web Designer in 2001. From the very beginning her approach was user-centered despite not being familiar with the now-common phrase of 'user experience'. In 2007 she finalized her study in Psychology and started working in the field of clinical Psychology. It was at this point that Martina's academic background and her passion joined and she started a career as UX Designer, being called "Conceptioner" at first. Since then Martina has contributed to the digital and service ecosystems of many recognizable companies such as eBay, PayPal, Emirates Airlines, Volkswagen, Telekom and many more. Finally, discovering a growing UX community in her birth-town Sofia and hosting the conference UX Sofia for the past few years has inspired her into giving something back by taking a more active role as a speaker and workshop facilitator.
Mariana Ivanova
Interaction Designer at SAP
I am a fairy. An experience junkie. Acro yoga monkey. Sound crazy, yes definately I admit I am crazy. Crazy about design thinking, passionate to spread it. Why? Because it's a simple tool for solving problems. But not just that, its a process in which people rediscover their creativity. And thats my mission to aspire creativity so that every human being has the confidence to create experiences in the world we live in.
