# Arnold Cartagena

> Senior platform engineer building production AI agents. Founder of Edictum — runtime governance that enforces deterministic contracts on every tool call an agent makes, outside the LLM.

Based in Bern, Switzerland. Focused on runtime governance, tool-call safety, and platform engineering for AI agents.
