Software designer, cook, baker and amateur bricklayer.

I'm Jesus Calamani, a software developer and entrepreneur based in São Paulo, Brazil. As a programmer, I am passionate about exploring new technologies and creating innovative solutions. I am dedicated to pushing the boundaries of what is possible, always seeking to learn and grow in the ever-evolving field of software development.
