Hi there, I'm Rubin 👋

Robotics Engineer | Embedded Software Engineer

Email LinkedIn

I'm a robotics engineer passionate about embedded software development and robotics. I enjoy building projects that bridge hardware and software, from microcontroller firmware to robot navigation. My work spans embedded systems (STM32, AVR, PIC, ESP32), single-board computers (Raspberry Pi, NVIDIA Jetson Orin), and robotics software (ROS2, OpenCV, Nav2).

🔭 Current Focus

  • Deepening my knowledge of FreeRTOS and real-time systems
  • Learning FPGA design with Verilog/VHDL
  • Building more embedded and robotics projects
