Dennes Torres

Data Platform MVP

Dennes is a Brazilian software architect and Data Platform MVP living in Malta who loves SQL Server and software development and has more than 20 years of experience. He moved to Malta after more than 10 years leading devSQL PASS Chapter in Rio de Janeiro and now is a member of the leadership team of MMDPUG PASS Chapter in Malta organizing meetings, events, and webcasts about SQL Server. He is an MCT, MCSE in Data Platforms and BI, with more titles in software development. He can be found speaking in SQL Saturdays around Europe”
However, you seem to want more details.

I’m 43 years old, I have worked in the IT area since I was 13, mostly in the training area (yes, delivering training at 13) and as a consultant. I was an experienced software architect and trainer working with VB 6 and COM+ in 2002, when .NET arrived and Brazilian community was born at the same time. I was among the first ones in Brazil to deliver .NET training.

Later, in 2008, I was in Los Angeles attending the conference where Microsoft disclosed for the first time Windows Azure (that was the name at that time) and when I returned to Brazil I was the first one to deliver an Azure technical session to a room full of people keen to understand what was the “operating system in the cloud” everyone was talking about.

My biggest community achievement was when, in 2008, I helped to organize an event for the launch of SQL Server 2008, Windows Server 2008 and .NET (3, if I’m not mistaken). The idea was to have local events all around Brazil, deliver one remote session directly from Microsoft Brazil headquarters and complete with local sessions. Microsoft was expecting maybe 30 simultaneous events. I was able to join venues (universities) with speakers and organized 59 events, reaching a total of 105 simultaneous events organized by Brazilian community.

More recently I decided to escape from the Brazilian struggle against the communists and came to Malta, working as a software developer, but now responsible for planning and executing the migration of Lopoca Gaming production system to the cloud.
