I am an IoT & Hardware Engineer experienced in firmware development, hardware interaction, and real-time embedded systems, with a strong focus on reliability and practical deployment.

Experience

Embedded Software Engineer
March 2025
 — 
March 2026
Aura Intelligent

Developing for the 'Aura Smart Farm' ecosystem. Responsible for firmware implementation, hardware validation, and technical support throughout the product lifecycle.

  • Supported the transition of IoT devices from prototype to mass production by validating hardware designs and optimizing firmware for stability.
  • Coordinated with PCB/SMT factories to troubleshoot assembly issues, verify component quality, and ensure production standards.
  • Assisted sales teams by defining technical specifications for contracts and provided on-site debugging/maintenance for key client deployments.
  • Deployed and maintained LoRaWAN sensor nodes across multiple farm sites, ensuring 24/7 connectivity and reliable data transmission.

Projects

STM32WL Low-Power LoRa Sensor Node
March 2025
 — 
March 2026

Deep-dive technical implementation for the Aura mass-production sensor device.

  • Developed STM32WL55 firmware using STM32 HAL and Semtech LoRa stack.
  • Configured Dragino gateway image to run ChirpStack and MQTT data forwarding.
  • Configured periodic wake-up using RTC timers for battery-powered sensor operation.
  • Designed 4-layer PCB layouts focusing on RF impedance matching (50Ω) and signal integrity for production.
ESP32 Audio Monitor & Relay Controller
March 2025
 — 
March 2026

Integrated real-time sound monitoring and environmental control system for high-efficiency bird nest farming.

  • Developed FreeRTOS-based firmware on ESP32 to handle concurrent tasks: high-speed ADC audio sampling and relay control logic.
  • Interfaced with analog measurement amplifiers to capture bird nest sounds, implementing digital signal thresholding for event detection.
  • Designed smart relay control circuits to automate environmental equipment (humidifiers, fans) based on sensor logic.
ESP32-Based Open-Source Drone
May 2024
 — 
March 2025

End-to-end embedded project building a complete quadcopter drone based on Espressif open-source ESP32 drone platform.

  • Built a complete drone system using ESP32 including flight control and communication.
  • Designed schematic and PCB layout for drone electronics and performed hardware bring-up.
  • Developed and modified embedded firmware in C based on Espressif open-source projects.
  • Integrated IMU sensors, ESC motor drivers, and control logic.
  • Tuned control parameters and performed testing on real hardware.
FPGA Audio Processing on Zynq-7000
June 2025
 — 
September 2025

FPGA-based digital signal processing project using the Xilinx Zynq-7000 platform.

  • Implemented FIR filters and matrix operations in programmable logic.
  • Used PetaLinux to configure the processing system and manage audio data flow.
  • Transferred audio data from Linux user space to FPGA logic for real-time processing.
  • Verified functionality through simulation and on-board testing.
