I design it and I ship it as working code, built with AI — from the company side of a hiring marketplace to monitoring tools for vessels and power plants.

03 — Testimonials
“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”
“What I enjoyed most working with Matheus was how creative and fast he was. We would discuss an idea by morning and by afternoon he already had 3 great variants to show us.”
“Matheus brings a great ability to simplify complex technical challenges into intuitive user experiences. His work on NautIQ and EnergetIQ combines thoughtful design, creative problem-solving, and strong collaboration with engineering and product teams.”
“I can't recommend him highly enough. He's seriously good at what he does.”

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.
