EXPERIENCE. CURIOSITY. PRACTICE.

Building platforms.
Evolving how I work.

I build and operate platforms, combining a deep understanding of systems with automation and the deliberate use of AI agents.

I develop my own tools to support this work, running AI agents in isolated environments with explicit controls.

AgentCLI — my engineering workspace

I have reshaped my daily engineering workflow around working with Codex and Claude. I define the tasks, provide the system context and review the results. The agents contribute to the work; technical decisions and responsibility stay with me.

AgentCLI is my own tooling for running agents in isolated, controlled project environments. I developed it through hands-on use, refining it as new needs emerged. It gives this way of working a structure I can manage.

Hermes is my personal assistant on Matrix. She monitors and coordinates projects through AgentCLI, bringing questions and approval requests back to me so I can stay involved across ongoing tasks.

I work in Zurich and live in Locarno.

Away from the keyboard, I find balance in the mountains of Ticino.
