I am Daniel Alfocea, known for years as cr0hn

Twenty years turning technological complexity into decisions you can actually make.

I used to build and break systems. Now I help decide what to do with them. Every day I write one thing about AI, security and applied technology in Vamos al lío. Three minutes, and it is dense.
