What leaders and peers say.

  • Natália SteinAgile Project Lead II · MB Labs

    I'd like to formally recognize the excellent work you presented today to Cinemark's leadership. A week ago we talked about the challenge of building a tool to help leadership govern the project. What you delivered today far exceeded my expectations. The solution is fantastic and will be essential for our time tracking, team monitoring and overall project management. Beyond meeting the main goal with excellence, I want to highlight your proactivity and systemic vision. On your own initiative, you identified improvement opportunities and built tools for the Quality (QA) team. The impact is huge: you brought standardization, speed and full transparency to the QA flow, value so clear that your solution will be scaled and shared with other teams in the project. Congratulations on your dedication, the technical quality of the delivery and your proactive attitude. It's a privilege to have you on the team and to see the level of maturity you brought to this challenge.

    I had the opportunity to work with Matheus, known as Bonotto, and I can say he is an extremely competent and collaborative professional. He always contributes a lot to the team, communicates clearly and efficiently, and brings ideas that add real value day to day. He also stands out for supporting leadership whenever needed, showing proactivity and commitment. Another strong point is how he uses AI to optimize processes and get work done faster and more efficiently. He made a very important contribution to the Bullla project, adding a lot to the deliveries and to the team's initiatives. Without a doubt, Bonotto makes a difference in the team and in the workplace.

    With Bonotto back on the team, we could use his knowledge to build tools that support every stage of the process, achieving a huge performance gain, on top of his collaborative approach in every activity of the quality process. He is a dedicated professional, highly motivated to help everyone.

  • Priscila RoballoAgile Project Lead · MB Labs

    Bonotto, you stood out immensely as a well-rounded professional and a key part of our delivery quality. I want to highlight three pillars that make you a great professional: Initiative and proactivity: you don't wait for problems to happen; you anticipate scenarios, propose improvements and act with a lot of autonomy. Process automation: your ability to automate processes has saved us time and raised the team's technical maturity. Commitment and engagement: it's clear how dedicated and engaged you are. You embrace challenges and deliver every task with excellence and on time. Thank you so much for your time with us on the project, for your daily dedication and for always playing as a team, Bonotto! We're proud to have had you with us. I wish you every success in your next cycles! I hope to have the honor of working with you again, and know you can always count on me.
