What I actually do: Most freelancers just snap pre-built modules together and call it a day. I design systems from the bare copper up. I am a mechatronics and PCB designer specializing in bridging the gap between custom electronics, mechanical kinematics, and firmware. If you are stuck trying to get a prototype off a breadboard and into a functional, lab-ready product, that is exactly where I step in. Here is what I deliver: --Custom PCB Design (KiCad & EasyEDA): 4-layer routing, impedance matching, and strict DFM. I build mixed-signal boards and custom carrier boards, keeping noisy power lines isolated from your sensitive RF antennas. --3D CAD & Mechanical (Fusion 360): Parametric modeling, rigid enclosures, and complex kinematic joints. I don't just make it look good; I simulate moving parts and clearances to ensure it actually fits together in the real world. --Embedded Hardware: Integrating ESP32 controllers, motor control loops, IMUs, and complex sensors without the noise. Note: I specialize in embedded mechatronics, battery-powered robotics, and consumer electronics. I do not design 230V AC mains or industrial high-voltage power grids. Let's stop fighting with off-the-shelf parts that don't fit your project. Send me a message with your technical constraints, and let's engineer a real solution.
