At Powermig Robótica e Soldagem - A Lincoln Electric Company, I develop and model functional parts and devices using DfAM for metal processes, including WAAM and MPBF, and polymer processes.

I calibrate and operate industrial 3D printers, laser engraving and cutting machines, and robotic devices to support rapid R&D validation.

At Araújo Engenharia, I researched technologies, created manufacturing and maintenance procedures, and worked on 3D modeling and mechanical design. I also operated 3D printers and inspection robots, and developed technologies and devices for field use.
