A bit about me
I started coding because I wanted to understand how AI tools actually work. Not at a surface level, but what happens when you type a prompt and it generates code. That question led me down a rabbit hole of reverse engineering, prompt analysis, and eventually building my own tools.
Beyond open source, I build products. ZeroLeaks helps companies test whether their AI prompts can be extracted by attackers. Zero Calendar uses natural language to create events without needing to click through date pickers. I like building tools that solve real problems.
I'm 16, based in Spain, and mostly self-taught. I learn by building things and breaking them apart to see how they work. Always looking for interesting problems to solve and people to learn from.
