14 public repositories

I build software and work with the systems that run it.

At EnfoquesTIC, I work as a developer and sysadmin. I build firmware and apps for connected devices and develop backend services. I also manage Linux servers.

I started most of my public repositories as tools I needed myself. Some have since become products, including PlexusTerm.

public repositories: 27
languages in them: 18
on GitHub since: 2019
