"Diogo is an exemplary security professional who has the dual capabilities of being extremely technically adept and being able to explain high level concepts in a well thought out/digestible manner. I routinely receive security reports from Diogo, each are well researched to show the direct impact the issues at hand may have. He has been an outstanding teammate and is routinely complimented in security and engineering spaces for his efforts. If he ever decides to move on (which I truly wish he doesn't) he would be an asset to any security team."

"I had the pleasure of working closely with Diogo from his time at NCC Group, I was his direct manager where he held the position of Security Consultant on our team. From the outset, Diogo distinguished himself as a dedicated, proactive, and reliable team player who consistently delivered high-quality work and always approached their work with a positive attitude, attention to detail, and an outstanding ability to handle complex tasks efficiently and most importantly, in a very professional and ethical way, always keeping the client focus. I am sure that Diogo will be a valuable asset to any organization fortunate enough to have him on board. I would recommend him as many times as needed on any organization."

"Diogo is a detail-oriented and impact-focused Application Security Engineer. During my short time managing him at Remote, Diogo showed end-to-end project management and delivery skills. He went from requirement scoping to a list of proposed solutions and proof-of-concept implementation all by himself, distilling relevant information from loosely-defined goals. Diogo also showed strong business-orientation by trying to understand the why of pursuing something before starting to research the problem space and relevant solutions, showing how much the wider impact of his work is important to him. I would recommend Diogo if you are bootstrapping a Security team in your company."

"Diogo is a very capable and detail-oriented engineer who contributed a lot to the stability and security of our platform. As a manager and tech lead, I loved that Diogo is a self-starter (...self-goer and self-finisher, lol) and required pretty much zero hand-holding when digging into the most obscure rusty parts of the platform. On the security side of things, Diogo was proactively monitoring our logs, caught at least one in-progress hacking attempt and implemented measures to stop it, as well as found and closed numerous other security issues that nobody else on the team would have looked into. This is a well-deserved glowing recommendation."

"I met Diogo when he was studying Computer Science and Engineering. Later, I have been working with him on a few projects. Diogo is hard-working, focused, and resilient; a problem solver. He is always ready to help and take on new challenges. His expertise in computer security and DevSecOps has been decisive in the projects we worked on together. Diogo is the computer security expert to have in any engineering team."

"Diogo has been a great contributor to Bubblehouse's security. He finds vulnerabilities that impact the platform and implements the remediations swiftly. He also develops new logic to prevent against attacks, making them more resilient including 2FA, rate limiting, bruteforce protection and more. Overall, great professional!"

"Diogo is a hardworking professional that strives for having an organized project and workplace. His wide skillset makes him achieve great results, even in areas that may not be his expertise. His determination to keep learning makes its way in seeing him often participating with solutions and valuable input. Overall great professional and person."
