Hey! My name is Mateus Araújo and I am from Portugal 🇵🇹!

I'm a multidisciplinary engineer passionate about building robots from the ground up, from custom PCBs and embedded firmware to ROS2 software, perception, and motion planning.
I love the intersection of robotics, AI, and hardware, and I enjoy turning ideas into real working machines: robotic arms, mobile robots, smart IoT devices, and anything that moves, senses, or communicates.

Let's connect! I am always excited to collaborate, learn, and build cool things with great people.
