About
I am an Electrical Engineer specializing in electronic hardware and PCB design, with a focus on RF, high-speed interfaces, signal integrity, embedded systems, and manufacturable electronic products.
I support both complete hardware development and focused engineering work such as PCB design review, troubleshooting, electromagnetic simulation, signal-integrity analysis, layout optimization, and preparation for manufacturing.
My work covers the complete hardware development cycle, including system architecture, component selection, schematic capture, multilayer PCB layout, power architecture, prototype bring-up, debugging, validation, DFM/DFT, and manufacturing release.
A recent project involved the electromagnetic analysis and optimization of a GMSL2 serializer-to-FAKRA PCB interconnect operating up to 6 GHz. I developed a KiCad-to-openEMS simulation workflow to evaluate S-parameters, return loss, impedance, transmission-line geometry, connector launches, via structures, anti-pads, and reference-plane discontinuities.
I also develop embedded and industrial hardware using STM32 and ESP32 platforms, cellular connectivity, GNSS, LoRaWAN, CAN, RS-485, Ethernet, BLE, Wi-Fi, sensors, industrial interfaces, low-power electronics, and battery-powered systems.
Typical projects I support include:
— Complete schematic and PCB development
— RF and high-speed PCB design
— Multilayer and controlled-impedance layouts
— PCB design review before fabrication
— Existing hardware troubleshooting and redesign
— Signal-integrity and electromagnetic analysis
— Embedded and industrial IoT hardware
— Power-management circuits
— Prototype bring-up and validation
— BOM optimization and component selection
— DFM, DFT and manufacturing documentation
I have experience across industrial R&D, freelance engineering, hardware validation, and test engineering, including two years in R&D at Furukawa Electric.
My main engineering tools include KiCad, Altium Designer, openEMS, Python, EasyEDA Pro, and ParaView. I also maintain my own electronics bench with an oscilloscope, spectrum analyzer, soldering equipment, and rework tools for prototype assembly, bring-up, troubleshooting, and validation.
My objective is not simply to complete a PCB layout, but to deliver hardware that is electrically robust, manufacturable, testable, and ready for the next stage of product development.
If you have a new hardware design, a PCB approaching fabrication, or an existing board that is not performing as expected, I can review the requirements and recommend the most effective path forward.
