- João Vitor Brietzke de LimaCo-Founder and COO • Nexus Software Development
I had the chance to supervise Victtor, and from the very beginning it was clear how dedicated, committed, and focused he is on doing his absolute best. He’s the kind of person who is never satisfied with just ‘ok’, always looking for ways to grow and deliver more quality in everything he does.
Another thing that really stood out to me was his sincerity and transparency. When something wasn’t right, Victtor didn’t pretend everything was fine — he put the issue on the table, with respect, and already came with suggestions on how to improve it. This created a much lighter and more collaborative environment, because we all knew we could truly count on him.
Beyond his technical competence, he is a person of strong values, who takes what he does seriously and genuinely cares about the people around him. I have full confidence in recommending Victtor for any challenge he chooses to take on. Anyone who has the opportunity to work with him will definitely gain a lot.
