I am passionate about technology and software development, with hands-on experience in designing and implementing innovative technology solutions. During my degree in Information Systems Engineering at the National University of Costa Rica, I have been able to develop technical skills in multiple languages and frameworks, such as TypeScript, C#, Python, ReactJS and ASP.NET, and I have applied agile methodologies (SCRUM) to manage complex projects. During my internships at Lealto and the Ministry of Public Works and Transport (MOPT), I worked on the creation of efficient management modules and systems, strengthening my ability to adapt, solve problems, and collaborate effectively in diverse teams. My approach combines continuous learning with communication and leadership skills. I seek to contribute my enthusiasm and experience in projects that drive digital transformation and optimize business processes.
