Marcelo S. Ancelmo has 20 years (and counting) of IT experience and has done a bit (or should we say a byte) of everything.

A good old-fashioned troublemaker, he started his professional career as a Java programmer, played a lot of the architecture game (which he still does today), worked into middleware (and do not regret it), built some great teams, done infrastructure and operations work. He also have done a lot of troubleshooting and performance assessment. Worked as a consultant, delivered a lot of training, has been a mentor, and spoke at some conferences.
He is deeply engaged with the software community, joining Meetups everywhere he goes, teaming up with JUGs, and organizing events when he have some spare time

Currently he is working as the Head of Solution Architecture at KPMG Switzerland, helping the company drive their DevOps transformation, still learning everything that is possible and enjoying all the bumps that come with it.
