About

A mechanical engineer who carries a part from the 3D model all the way to the machined, tested and measured result.

I am a mechanical engineer graduated from the Universidade Federal de Ouro Preto, working across automotive, aerospace, naval and robotics projects. My work sits where CAD, simulation and manufacturing meet: I model in SolidWorks, Inventor, Fusion and Siemens NX, validate with Ansys, then build the part on a CNC machine or a 3D printer and measure it on the bench.

At Luzagroup I automate design processes with knowledge-based engineering in Siemens NX, which lets section updates happen automatically instead of by hand, and I work on Body-in-White and interior trim parts where Class A surface quality is the requirement. Before that, at LAESS, I ran the test side of Brazilian Air Force projects — photogrammetry of parts, aircraft spring testing, spring constants with their uncertainties, and static, transient, flexible body and fluid simulations.

I also build the control side: for a satellite attitude platform I modelled the dynamics in MATLAB and Python, wrote the C++ firmware on Arduino, and got a response under three seconds with no overshoot. I write Python and SQL for data analysis, and I report results clearly enough that other people act on them.
