Ruby on Rails architect, AI toolmaker, and former CTO.

I'm Mario Alberto, a software engineer and entrepreneur based in Colima, México. I'm the creator of Rails MCP Server and former CTO/co-founder of Aoorora, where I architected a core banking platform in Ruby on Rails that enabled lending startups to build on modern, secure infrastructure. I spend my time at the intersection of Ruby on Rails and AI—building tools that help developers work smarter. When I'm not writing code, I'm documenting territory, popular culture, and memory through photography.
