Hello! I’m a hardware engineer with many projects behind me, some simple, some highly complex, but all completed with great care and attention to detail. I work closely with a driven group of young engineers on developing hardware and software for diverse projects. We have deep experience in designing reliable, production-ready hardware and firmware using modern MCUs (ESP32, STM32, TI, C2000), high-power topologies, battery systems, and a wide range of communication protocols. Our lab is fully equipped for prototyping, testing, and validation, including oscilloscope work, precision measurements, firmware bring-up, and full board bring-up. Over the years, I (and we) have gained experience designing high power, mixed-signal PCBs where signal integrity and EMI problems can occur. Technical Expertise: Hardware & Power Electronics • Topology selection: buck, boost, flyback, SEPIC, PFC buck, forward, synchronous drivers • Wide range power design up to 5 kW, switching frequencies up to 5 MHz • Battery systems: BMS, balancing, charging, MOSFET drivers PCB Design • Professional PCB layout using Altium Designer and KiCAD • High density, mixed signal, high current, high voltage, and EMC safe design • Rigid flex, microcontroller modules, RF layouts • Full DFM/DFT optimization for production Communication Protocols • CAN, I²C, SPI, UART, RS485 • Bluetooth, Wi Fi • Ethernet Software & Simulation • MATLAB, Simulink, PSpice • LTspice, TINA, • Firmware bring up Prototyping & Testing • Soldering, rework, fault analysis • Gate driver tuning, feedback loop stabilization • Load testing, thermal evaluation, EMC preparation If you need a reliable, complex PCB design that can pass EMC tests, along with all documentation required for manufacturing and assembly, you are in the right place. We’d be happy to take on your challenge! Best regards!
