Technical lead

Diego Souza

Technical lead · T3N

Diego Souza is responsible for T3N. Twenty-four years in technology infrastructure, ten of them in financial services — until [MONTH/2026], IT manager at an independent asset manager, with a scope covering infrastructure, information security, telecom, business continuity, budget and contracts.

Before that, at L'Oréal, he moved through the technical ladder of the Brazilian operation until coordinating IT infrastructure: networks, data center, virtualization and disaster recovery. The foundation was built in technical support at GPA and BNY Mellon, between 2002 and 2007.

T3N applies that background to organizations that run Microsoft environments without an in-house infrastructure team.
