Profile
Passionate about technological development, I am dedicated to create and improve software solutions. In my spare time, I develop applications, design websites and repair computers. I stay on the cutting edge of emerging technologies such as Bun, Astro and AI. Java is my programming language of choice, but I adapt easily to diverse technology environments, including infrastructure and front and backend development. I am committed to continuous learning, closely following the latest technological innovations. I am honest, friendly and empathetic, and value collaboration and building relationships of trust and mutual respect.
