🚀 About Me

I’m a Full Stack Developer focused on building secure, scalable, and well-architected applications, combining frontend, backend, and security best practices.

I work mainly with JavaScript, TypeScript, React, Node.js, and Next.js, developing REST APIs, integrating SQL and NoSQL databases, and applying clean code, performance optimization, and security-by-design principles.

With a background in Computer Science and Cybersecurity, I bring a DevSecOps mindset, especially valuable in critical environments such as healthcare, where availability, data protection, and reliability are essential.
