🦾 ROHAMID — Electronic Hardware & Firmware Engineer

🔧 Embedded hardware and firmware engineer with over 15 years of experience in embedded programming, specializing in STM32 microcontrollers and Embedded C. Experienced in full hardware + firmware delivery: schematic & PCB design in KiCad, discrete-IC designs, firmware architecture, device bring-up and debugging. Delivered hundreds of projects from prototypes to production.

⚙️ Core Expertise

  • 🧰 STM32 families (firmware architecture, HAL/LL, CubeMX)
  • 🎛️ STM32-based embedded GUI design: TouchGFX, LVGL
  • 🛠️ Embedded C (device drivers, BSPs, bootloaders)
  • 🔌 RTOS (FreeRTOS) and bare-metal systems
  • 🔋 Peripherals: UART, I2C, SPI, CAN, ADC, DAC, PWM, timers
  • 🔍 Hardware design: schematic capture, PCB layout (KiCad), BOM, assembly
  • 💡 Debugging: SWD/JTAG, logic analyzers, oscilloscopes
  • 🧪 Power management, low-power design, mixed-signal considerations
  • 🛰️ Version control (Git), CI basics, hardware bring-up processes

🧭 Tools & Technologies

  • 🖥️ KiCad, Altium (EDA tools)
  • 🛠️ STM32CubeMX, STM32CubeIDE, Keil MDK (µVision), OpenOCD (firmware/toolchain),
  • 🖥️ TouchGFX Designer, LVGL (GUI design)
  • 💻 C, C++ (embedded), 🐍 Python (scripts, tests)
  • 📈 Oscilloscope, 🔌 Multimeter, 📊 Logic analyzer, 🔧 Soldering stations
  • 🏭 PCB fabrication and assembly workflow

🧩 Selected Project Types

  • 🚗 Motor controllers and power electronics with STM32 drivers
  • 🤖 Robotics and motion-control systems (sensors, actuators, closed-loop control)
  • 🔋 Battery management and charging systems
  • 🌡️ Sensor nodes and custom communication firmware
  • 🖥️ Embedded GUI applications (TouchGFX, LVGL)
  • 🖱️ USB device / HID / CDC firmware
  • 🔀 Discrete IC-based interface boards and level-shifters
  • 🛠️ Production-oriented firmware with bootloader and OTA update paths

📈 Workflow & Practices

  • 🧱 Modular firmware architecture and reusable drivers
  • 🧪 Hardware-first validation, then iterative firmware integration
  • 🛠️ Clear schematics, DRC-checked PCB layouts, and detailed BOMs
  • ⚙️ Automated builds, unit tests where practical, and hardware test vectors
  • ✅ Emphasis on reliability, maintainability and manufacturability
