About this blog

The goal of this blog is to document the projects I'm doing in my free time and the things I learn. I don't intend for it to be an updated blog since I am aware that it takes a long time, but I would like to have it as a place to save the projects and notes on problems or stuff that have taken me time to learn or solve. Although documenting takes time, I think it is also a way to establish knowledge and finish filling in those gaps that exist during learning or the process of doing something.

About the author

I'm a computer Engineer specilized in cybersecurity. In recent years my interest has expanded to include mechanical design, electronics, and hardware. I also have experience in programming and configuring inverters for electric motors as I have been building electric motorcycles on my free time.
