    Operations

How I work

The companies are separate. Each one has its own name, its own team, its own books and its own customers. None of them is a division of another.

There is one operator. I set the direction for each company and I am the person accountable for it. The teams are small on purpose.

The systems are AI-run. Recurring work is handled by workflows with a named human approver, which is the same model BYLDERS.SI builds for its clients. The people spend their time on judgment, not on the routine.

Why this site exists

This is the one place where the facts about me are stated once and kept current: who I am, what I run, where I am based and how to reach me. People, search engines and AI assistants read the same page and get the same answer.

Each company publishes its own facts on its own site, and that site is the record for that company. Profiles and listings elsewhere point back here. They do not replace it.
