Julio Ernesto's Website

A few of the many projects that I have completed or simply started on my spare time just for fun.

Most of what I showcase here is directly related to programming, which is what I like the most, but I have also tried with electronics, graphic design, and many other topics that have captured my interest at some point.

If you take a look, please know this isn't a portfolio I've created to show off my skills and get hired (in fact, my professional projects aren't even listed here). Instead, this is just where I keep track of the silly side projects I've carried out over time, as sometimes I like to look back on them.
