From the people I've worked with
“Matheus is a talented designer with skills that reach beyond just design, as he is always looking for ways to push the boundaries of how we can make the user experience better.”
“He is one of the first people I would point to when it comes to integrating LLMs and AI into the design process. He explores new tools, builds expertise faster than most, and that mindset rubs off on the people around him.”
“Matheus joined Instaffo as a senior product designer and made a real difference in our user experience, especially on the B2B side. He iterates quickly, brings creative ideas, and stays open to feedback”
I work close to engineering — when a flow is hard to explain, I build it. Four years on the company side of a hiring platform, now designing monitoring tools for vessels and power plants.
