About me

About Me

Full-Stack Developer

As a Full-Stack Developer, I combine web and back-end development skills to create complete and efficient solutions. On the front-end, I build attractive and functional interfaces using technologies such as Angular/React, ensuring a fluid and responsive user experience. On the back-end, I develop and maintain APIs and systems using Java and Spring Boot, manage relational and NoSQL databases such as MySQL and MongoDB, and focus on server optimization and security. My integrated approach allows me to develop robust and well-balanced applications, from the user interface to the server.
