What kind of product work do you do?
I build operating surfaces: the product layer where people, data, approvals, and automation meet.

Ask about the work before scheduling a call.
Ruben has an AI interview page. For this standalone version, this page gives visitors strong prompts and grounded answers without pretending there is a live AI backend.

Use these prompts to understand how I think, build, and manage risk.
What makes your work different from a normal portfolio?
The focus is not only visual design. I show how decisions, state ownership, QA, security, and launch gates fit together.
How do you use AI?
I use AI to accelerate research, drafting, QA, and bounded execution, but consequential actions need explicit approval and evidence.
Where are you strongest?
Ambiguous operational problems where the team needs product judgment, software execution, and a safe path to launch.
