I'm a cybersecurity researcher and OSINT operator based in the United States. I specialize in offensive security, open source intelligence, infrastructure reconnaissance, and custom tool development.

I've mapped the digital infrastructure of 69 countries, indexed 3 million+ developer profiles from public sources, and built reconnaissance tools that scan at scale. My work has uncovered exposed government systems, unsecured databases, and critical infrastructure vulnerabilities across Latin America, the Caribbean, and beyond.

I run my own bare-metal server with 40+ containers handling everything from dark web intelligence collection to wardriving data pipelines. Every tool I use, I either built or modified. Every dataset I sell, I collected and curated myself.

I write about cybersecurity, OSINT methodology, and the things I find on Substack. I publish open source tools on GitHub. I teach what I know through courses on this platform.

I don't work for a company. I don't have a team. I have a server, a set of skills, and a very long list of things that shouldn't be connected to the internet but are.
