Electrical & Electronic Engineering | Altium Designer, PCB | Embedded

Hi, I’m am an American U.S. based medical device engineer with 15+ years of experience designing, testing, and validating PCB-level electronics for medical, industrial, military, and R&D applications. I specialize in EagleCAD/Fusion360 (primary) and Altium-compatible designs, and have hands-on experience with micro-soldering and bench-level troubleshooting and repair (facilities can be arranged for the right project). If you need help turning a schematic into a manufacturable board, debugging an existing design, or setting up automated testing for your hardware, I can support you from system concept through prototype, verification, and market release. Transparent communication and regulatory-grade documentation come standard—you’ll always know what’s been done, what’s next, and why it matters. Let’s get your design validated and ready to build.
