👋 Hola!Me llamo Iván y soy emprendedor, informático, tecnólogo e innovador 💻.Del 2014 al 2022 estuve estuve construyendo una fintech B2B2C en el mundo de los pagos y del lending online. La empresa es la líder indiscutible en su sector en España, rentable casi desde el principio y sigue creciendo, en negocio, mercado, productos y rentabilidad 🚀.Tuve diferentes roles de liderazgo en torno a la tecnología, la innovación, el desarrollo de negocio y el lanzamiento de productos.En ese proyecto:1. 💾 sufrí de primera mano las limitaciones de la tecnología legacy con la que se construyen los raíles financieros tradicionales,2. 🏦 viví todas las ineficiencias a la hora de emitir y colocar deuda o activos financieros a entidades o inversores profesionales,3. 📜 diseñé el programa de actividades y toda la documentación técnica de una entidad financiera de pagos regulada por el Banco de España y sufrí lo indecible con el proceso burocrático para obtener la licencia (tan largo, que, de hecho, no vi el fin 🤣).Descubrí entonces el mundo del blockchain y comprendí que es la tecnología sobre la que se van a construir los nuevos raíles financieros.El blockchain ofrece:1. ⚡️ dinero que se mueve a la velocidad de Internet 24x7 y con comisiones bajas,2. 😌 libros de cuentas compartidos entre los actores que se relacionan en un determinado proyecto lo que elimina la necesidad de duplicación de información y de conciliación y simplifica enormemente la liquidación,3. 📈 un reporting mucho más sencillo, transparente e inalterable y4. 🕸️ descentralización y acceso sin tener que pedir permiso a nadie.El blockchain hace innecesario:1. 🤝 el uso de multitud de intermediarios y2. ♻️ el papel utilizado para contratos y demás burocracia porque el soporte digital es persistente, inmutable e irrefutable.Ahora estoy centrado en aprender, compartir y desarrollar proyectos con esta tecnología, especialmente aplicada al mundo financiero y a la tokenización de activos.Puedes aprender conmigo en mi newsletter 📩quincenal gratuita 👉 https://www.ivanparraga.com/#/portal/signup¿Cómo puedo ayudarte?
