The Operator

Ruben
Dos Santos

25+ years in IT and a former CIO in Switzerland, now building from Portugal across Europe. RJDSM is operated as a single-founder holding — a deliberate, hands-on studio for ventures in consulting, applied AI, digital identity and trust.

The aim is singular: make trust verifiable, and build the platforms European communities and commerce can rely on.
