About

Founder and Chief Executive & Technology Officer at Valcann, university professor at CESAR School, Visiting Fellow at the Massachusetts Institute of Technology (MIT) and Amazon Web Services Ambassador in Latin America. The curiosity that began in childhood, in front of a friend's computer, turned into a company, a doctoral thesis and a career devoted to turning knowledge into solutions that hold.

Brazil's first doctoral defense in Software Engineering

“I became interested in technology as a child, curious about a friend's computer. Since then, that curiosity has grown and borne real fruit: I founded Valcann, a cloud-computing company where I serve as CEO.”

In August 2023, Carlos Diego defended the thesis “Capacity Planning of Cloud Computing Workloads” — the first thesis of a Professional Doctorate program in Software Engineering in Brazil. A milestone for CESAR School and for the field.
