    With the experience I have, I have been able to notice that web development is divided mainly into two groups, those who design sites and / or web applications (front-end) and those who write the code. Some complement the others, however, in general, programmers are terrible designers and vice versa. And it is precisely in this gap where I intend to sneak myself. I am a Software Engineering graduate and I am currently studying a Master in Digital Marketing in Madrid, Spain. Although I am a programmer, I have also been designing websites since 2015. I currently develop plugins for Wordpress where I always do my best to merge an efficient product with an elegant and professional appearance. My work is always oriented to satisfy my client and my client's client.

    Mi viaje como programadora de .NET ha sido una emocionante travesía llena de aprendizaje y desafíos. Comenzó con una sólida formación en Desarrollo de Aplicaciones Multiplataforma durante mi Grado Superior, y desde entonces he forjado mi carrera en este apasionante campo. Mi primer encuentro con el mundo laboral tuvo lugar durante mis prácticas en ANOVO, donde tuve la oportunidad de sumergirme en el desarrollo de aplicaciones utilizando .NET. Fue allí donde mi pasión por esta tecnología comenzó a tomar forma, trabajando con Visual Basic. ANOVO reconoció mi potencial y me ofreció un puesto de trabajo, marcando así el inicio de mi andadura profesional en .NET. Mi siguiente destino fue INFORYDE, donde mi experiencia en .NET se expandió aún más. En INFORYDE, tuve el privilegio de trabajar con C#, un lenguaje de programación versátil y poderoso. Aquí, participé en proyectos cruciales para IBERDROLA, lo que me permitió aplicar mis habilidades en un contexto empresarial de gran envergadura. También hago grabaciones de audio con mi voz porque me gusta.
