Carlos A.

Embedded Systems & Control Engineer | Simulation, PCB, Firmware

You get a system that works, and you'll know exactly why it works. I design it, build it, test it, and hand you proof it's ready, not a guess dressed up as a deliverable. I move fast and explain things in plain terms, even the complicated parts. You'll never be left wondering what's happening with your project or why a decision was made. Most control problems are actually hardware problems, and most hardware problems show up as bad control behavior. I work on both sides, so I catch the real cause instead of tuning around it, and that's usually where other engineers get stuck. PCB design and firmware (Altium, KiCad, STM32, ESP32), control systems and simulation (MATLAB/Simulink, Python, ROS, HIL/SIL), and mechanical CAD (SolidWorks, Fusion 360) when your project needs the enclosure or mounting solved too. Every delivery ships with a test procedure, pass and fail criteria, and documented results, so you can verify it yourself. Mechatronics Engineer, Tecnológico de Monterrey, honors, top 10%. R&D intern at AIST Japan. Project work with John Deere, ABB, Parker Hannifin. Based in Ecuador, full overlap with US Central time. Tell me what your system needs to do, and I'll tell you what I'd deliver, in what order, and how we'll know it works.
