Javier Castillo

I am a Full Stack Developer with experience building end-to-end web applications, from architecture design to implementation and deployment. I work integrating APIs, databases, and modern services, with a focus on performance, maintainability, and user experience. I adapt well to collaborative teams, follow development best practices, and aim to deliver stable solutions that bring real business value. I am interested in remote or hybrid opportunities where I can continue growing professionally and contribute to well-structured projects.
