Embedded System Engineer | Access Control | C/C++ | PCB

I am a results-driven Embedded Software Engineer with 3+ years of experience specializing in real-time systems on ARM-based microcontrollers (STM32, Tiva-C). I develop efficient, reliable embedded firmware and implement robust communication protocols including UART, SPI, I2C, CAN (CAN-FD, UDS), GPIO, and watchdog timers (WDT). Key expertise and projects: • Designed and developed Multi-Sensor Camera and Full Height Turnstile Gate embedded systems • Implemented AUTOSAR-compliant CAN Time Synchronization modules for precise network timing • Built secure Access Control systems supporting OSDP and Wiegand protocols with Fault Management using non-volatile memory • Developed drivers for Laser Rangefinder sensors and integrated system watchdog timers • Engineered diagnostic CAN communication frameworks interfacing with NVIDIA Jetson platforms • Customized Yocto Linux builds on Raspberry Pi for advanced embedded applications • Contributed to PCB design, ensuring seamless hardware-software integration My technical toolkit includes C/C++, Python scripting, RTOS, and unit testing with Ceedling. I’m passionate about delivering scalable, production-quality embedded solutions tailored to your project’s needs. Let’s collaborate to bring your embedded system project to life with precision and reliability
