Software Engineer.
Frontend & Cybersecurity.
Hi, I'm Gabriel Machado. I build web apps people enjoy using, and I hold a Master's degree in Cybersecurity, a field I'm genuinely passionate about.

I'm a software engineer focused on the frontend. I like turning messy data into interfaces people can actually use: maps, feeds, dashboards.
In my free time, I also enjoy building websites for a few clients.
My Master's is in cybersecurity, which is why some of my side projects look at dependencies, pipelines and what could go wrong.
Most of what I build starts as a tool I wanted for myself, then ships for real.
Things I've built.
Live and in use.
From client websites to tools that collect thousands of listings a day. Click any of them to try it.
