IoT Security Specialist, Embedded Firmware Developer

I build secure IoT firmware and uncover vulnerabilities in smart devices. With hands-on experience in ESP32/STM32 (ESP-IDF, FreeRTOS), I focus on security from day one. I don’t just ship working code...
About this Gig

Custom ESP32 & STM32 firmware built secure from day one.


I write production-grade firmware in C/C++ using ESP-IDF

and STM32 HAL/CMSIS. Not Arduino sketches real embedded

code with FreeRTOS, proper error handling, and security

best practices.


What I build:

  • WiFi/BLE/MQTT/CoAP connectivity
  • Sensor integration & driver development
  • OTA update systems with rollback
  • Cloud platform integration (AWS IoT, Tuya, custom MQTT)
  • Secure boot & encrypted storage
  • FreeRTOS task architecture


Every firmware I write follows security best practices

because I also do IoT security audits.
