Most freelancers on Upwork will send you a folder with design files and let you figure out how to build it. I don't work like that. I am a Senior Engineer with a dual background in Electronics and Mechanical Design. I have my own lab (WhaleTechnologies) with soldering stations and 3D printers. I come from the Aerospace and Medical sectors. I use those standards to catch interference issues or mechanical misalignments early, so you don't waste money on bad manufacturing runs. My goal is to ship you a working prototype. I don't just design the circuit; I design the enclosure for it at the same time. I assemble the PCB, 3D print the case, and put everything together on my bench. This means when you receive the prototype, you can simply turn it on and verify it works. How I work: 1. Physical results. I don't stop at the schematic. I source components, solder the board, print the enclosure, and test the full assembly. 2. Integrated Design. I design the PCB (Altium/KiCad) and the Mechanical Enclosure (CAD) together. No more errors where the USB port doesn't align with the hole. 3. Verification. I use oscilloscopes and thermal cameras to check that everything actually works before I ship it. My Expertise: 1. Electronics: High-Complexity PCB Design (HDI, Rigid-Flex), Firmware (STM32/ESP32). 2. Mechanical: Enclosure Design, 3D Printing (SLA/FDM), Thermal Management. 3. Prototyping: I handle the entire build process in my lab in Spain and send you a unit ready to test. If you want a finished prototype and not just a zip file, let's talk.
