I am a hardware engineer with 10+ years of experience designing and bringing up complex embedded systems from technical specification and architecture to PCB design, validation, and production support. What I do: Design microcontroller- and microprocessor-based hardware for industrial, IoT, automotive-adjacent, and communication devices Own the full hardware cycle: component selection, schematics, PCB, bring-up, validation Work closely with embedded software teams on hardware–software integration Hardware & PCB Multilayer PCB design (up to 12 layers, controlled impedance, mixed-signal up to ~1 GHz) High-speed interfaces: USB 2.0 / 3.2, PCIe, Ethernet, SATA, HDMI, LPDDR4 DDR4 signal integrity modeling and timing analysis using Cadence Sigrity Power electronics: DC/DC, LDOs, power sequencing, thermal considerations EMC pre-compliance and debugging (including BCI testing) Embedded & Systems Platforms: STM32, ESP32, AVR, i.MX6, Raspberry Pi Firmware support: C, HAL, FreeRTOS, board bring-up, low-level debugging Embedded Linux systems and gateway-class devices Interfaces: SPI, I2C, UART, USB, SDIO, RS-232/485, Ethernet, PCIe Advanced & Domain Experience FPGA-assisted systems and hardware accelerator applications Automotive-grade hardware validation, DFMEA / FTA / FMEDA (Medini) Medical-related electronics (PPG, ECG, EMG) Industrial automation, IoT, telecom-related projects Tools & Bring-up Altium Designer, OrCAD / Allegro, SolidWorks, Git Professional lab equipment: oscilloscope, logic analyzer, signal generator Prototype assembly, rework, and debugging If you need an engineer who can design hardware, bring it up, debug real problems, and deliver a working prototype - I can help.
