Senior electronic design engineer with 20+ years of experience and 100+ product designs delivered for clients in more than 15 countries. I take products from concept to production: architecture, schematic, PCB layout, firmware, prototype assembly and bench testing, all done by me. You work directly with the engineer who designs your board, with no handoffs between team members. WHAT I DESIGN - Precision analog and mixed-signal: isolated measurement front-ends, 24-bit RTD and sensor interfaces, bio-signal (ECG, EEG) acquisition, linear opto-isolated signal paths - RF and wireless: BLE, Wi-Fi, sub-GHz, LoRa, NB-IoT and LTE-M, RTK GNSS, NFC. Custom PCB antennas, simulated, then tuned and measured on the prototype - Power electronics: buck, boost, buck-boost, SEPIC, flyback, H-bridge and cascaded inverters, MPPT solar, Li-ion charging and protection, PoE (802.3at/bt) - Embedded and high-speed digital: STM32, nRF52, ESP32, i.MX with DDR, embedded Linux, 10-layer, HDI, flex, rigid-flex and stretchable PCBs - Firmware: C/C++ on bare metal and RTOS, ultra-low-power designs, motor control, DSP, bootloaders and firmware update systems SELECTED RESULTS - BLE wearable sensor running 14 months on a CR2450 coin cell - Isolated SCADA measurement board holding ±0.1% accuracy next to VFDs and motor starters - 3-channel TEC controller holding ±0.05 °C at setpoint - 10-layer i.MX industrial SBC with DDR, deployed in hazardous locations - Cascaded H-bridge inverter reaching 2 kV from stackable low-voltage modules - RTK GNSS/IMU tracker with under 3 cm accuracy in open sky IN-HOUSE LAB Prototypes are assembled and tested in my own lab: pick-and-place, reflow and JBC rework for assembly; oscilloscopes, spectrum analyzers, VNA with antenna pattern measurement, EMC pre-compliance, electronic loads, precision bench meters and thermal imaging for test (Keysight, Teledyne LeCroy, Tektronix, Fluke, FLIR, Pico). Designs are verified by measurement, not only by simulation. HOW I WORK - Clear requirements and an honest feasibility assessment before design starts - Designs ready for manufacturing, with parts in stock and second sources - Design for compliance (CE, FCC, IEC 61010, IEC 61000) and support through certification - Complete documentation and editable source files; you own everything - Long-term availability for revisions and production support TOOLS Altium Designer (primary), KiCad; Keysight ADS, Ansys, COMSOL; SolidWorks; Keil, IAR, GCC, ESP-IDF, STM32Cube. SOFTWARE I also write the software around the hardware: desktop and web tools in C#, Python and JavaScript for test fixtures, production programming and device configuration.
