Hello, World!

Hi, I'm Eduardo Barreto!

Here I write about networking, cybersecurity, open-source tools, cloud, AI, tech culture, and whatever I'm currently learning or feel curious about — or just... life! My passion (among others!) is to make technology practical and approachable, regardless of your background. If something here helps you (or sparks an idea), that's a win. Questions, feedback, and topic suggestions are always welcome, feel free to reach out.
