    Greetings, I’m Yasmim Franceschi, an independent artist and creative freelancer from Brazil. I use my creativity and challenge myself to find new paths and possibilities to live authentically. My international journey started at age 17 when I moved alone to Israel and joined an international school project living and studying with people from over 40 different countries. Besides the extreme multicultural experience, I graduated from the International Baccalaureate (IB) program which gave me native level English proficiency. Then, I graduated with honors from Tel Aviv University with a B.A in Liberal Arts combining studies in Psychology, Philosophy and Digital Culture besides a few technical courses I took independently such as Cybersecurity, Programing (C and Python) and Calculus. My intellectual journey led me to a profound interest in Myth and the ways it is ingrained in our social systems, psyches and expressed through art. I began to question how myth manifests in a digital, technocentric culture. Thus, my freelance projects are usually exploring how technology is shaping new cultures. I recently completed a book called “Kialara: Art and Bitcoin” analyzing and reporting on the art of Max Mellenbruch, drawing new insights to help us understand how new digital cultures are being forged from tradition and where seemingly new contradictions of our age are forcing us to develop new cultural artifacts. Writing and researching in the field of visual arts led me to work a corporate job at the Museum of Modern Art of São Paulo, where I was supervising institutional relations. This position gave me strategic understanding of the cultural scene from direct experience working with artists, gallerists and art supporters. Besides working in the field of visual art, I have also worked as a journalist, publicist, blog writer, storyteller for games and other creative tasks. My passion is music and I’m currently devoting my free time and resources to developing my career as a singer songwriter utilizing all of my cultural and professional baggage to express my essence as an artist. My expertise includes: - Public Relations: Developed and executed press release strategies and materials for varied projects, such as the Booka app, Jon Redfern's musical release and Max Mellenbruch's Kialara latest releases. - Content Creation: I have recently completed a book (to be published soon) reporting on the first decade of the Kialara project and contributing with theoretical insights on the relevance of this project to cryptoart. - Creative Writing: Developed a storyline for the RPG game Mavia Heroes and cerated diverse blog posts for various clients. - Jornalism: Created a unique series of content on blockchain and society for the Dailycoin and contributed with articles to my city's local newspaper. I'm on the lookout for projects that allow me to use my creative and storytelling resources to amplify your goals. Let's connect!

    A guaranteed job by a father, friend and citizen working as a full-time translator. I've been learning English since I was 5 years old, but translating English content isn't my job; it's my life. It allowed me to thrive in this globalized and wonderful world. I translate various contents, with great knowledge in IT, Hardware and High-tech matters. With over two decades of gaming background in RPG, FPS, Strategy and Adventure, I might also be your best choice for such topics. At last, but not least, I'm a CBP (Certified Bitcoin Professional) and have been translating Blockchain, Cryptocurrency, Bitcoin and Economy-related websites, platforms and articles, while creating courses and educational content for the Brazilian audience since 2017. Got feedbacks? Great, let me know where I can improve! But remember that respect is the core or our civilization. Cheers!
