About

I’m Rubén Oliva. I build AI and data systems, then benchmark them until the numbers say something honest.

This is where I write down what survives that process: longer arguments, technical field notes, lessons from building, and the occasional story from outside the terminal.

What to expect

• Artificial intelligence without the theatre
• Agentic engineering, harnesses, and benchmarks
• Software and data systems in practice
• Notes on learning, work, and everything around it

The principle is simple: measure > guess.

You can follow the work behind these notes on GitHub or find the professional version on LinkedIn.
