I had the pleasure of working with Joao for the past ~2.5 years and during this time, I can confidently say that he is one of the best software engineers I have ever had the privilege of working with. Joao is an exceptional engineer with a keen eye for detail. He pays attention to even the smallest details without losing sight of the big picture, ensuring that our team's work is of the highest quality. This has been instrumental in getting our team to where it is today. He also has a knack for creating elegant implementations that not only solve the problem at hand but also anticipate future needs. What I admire most about Joao is his strong sense of responsibility for whatever project he is involved in. He is always willing to put in the extra effort to ensure that everything is done to perfection. His vast knowledge and experience in engineering have been invaluable to our team, especially while working on the big auth re-architecture. He constantly thinks about failure points and ways of improving our services to make them more secure, scalable, and resilient. He's also a great team player who is always eager to lend a helping hand and share his knowledge with the rest of the team. I would highly recommend Joao to anyone looking for an experienced, hardworking, and reliable software engineer. He is an asset to any team and I feel lucky to have had the opportunity to work with him and hopefully will get the chance to work with him again.

I've been working with Joao for almost a year and it's been an absolute pleasure to have him on my team. He's extremely knowledgeable, hard working and always thinking about how things can be improved. He's been a key contributor to the re-architecture effort of the DAZN Global Auth system, making it more resilient, easily extensible and less coupled to external dependencies. Next to the actual development work he's also been a keen mentor to some of the more junior people on the team, explaining our services and ways of working and helping them wherever they might struggle. His social skills and dry sense of humour make any project with Joao more fun - as well as the occasional after work dinner / and or drinks of course :)
