About Zakariae

Embedded Software Engineer – C Firmware & Validation

Specializing in low-level firmware development on STM32 microcontrollers, I am proficient in bare-metal C development, writing communication drivers (UART, SPI, I2C, CAN, 1-Wire), and software validation on real hardware.

During my experience at Schiller Medical, I contributed to the development of a critical embedded system for a defibrillator: low-level drivers, V-cycle architecture, unit testing with Unity/Ceedling, JTAG debugging, and real-time validation. At Capgemini Engineering, I developed in embedded C on microcontrollers for automotive lighting functions with real-time fault detection.

Currently, I am working on personal open-source projects to strengthen my embedded systems and low-level software development skills:

- Embedded Data Logger: github.com/zkariae/embedded-data-logger

- STM32 RFID RC522 Driver: github.com/zkariae/STM32_RFID_RC522_Reader

- STM32 ESP8266 UART Gateway: github.com/zkariae/stm32-esp8266-uart-gateway

My goal?

To help you deliver reliable, high-performance embedded products that comply with industry standards.

What I offer:
  • Firmware Development
  • Low-level driver design and development (SPI, I2C, CAN, UART)
  • RTOS porting and integration (FreeRTOS)
  • BSP and Hardware Abstraction Layer (HAL) development
  • Memory optimization and real-time management
  • Embedded Testing & Validation
  • Setup of HIL (Hardware-in-the-Loop) test benches
  • Writing test plans and validation specifications
  • Embedded unit testing
  • Code coverage analysis and automated regression testing
  • Real hardware validation (JTAG, oscilloscope, logic analyzer)
Available for missions in firmware development, embedded validation, or hardware/software integration — remote or on-site as needed.
