Sergiu P.

Embedded Software Engineer

I'm an Embedded Software Developer with over 7 years of experience, specializing in C/C++ development for the STM32, nRF52, and ESP32 MCU series. My work involves designing firmware for embedded systems and integrating technologies like Wi-Fi, Bluetooth, ADC, UART, and many other essential peripherals. Throughout my career, I've taken on diverse projects, including the design of a CAN bridge using ESP32, full software development for an nRF52-based clicker device, and an ESP32-based toy featuring Machine Learning-powered wake-up word detection. I've also worked on embedded Linux projects, creating kernel modules for camera sensors, developing custom Linux images with Yocto, and integrating drivers for PCBs and peripherals. Additionally, I bring experience in hardware testing, having developed test rigs using Robot Framework and Raspberry Pi, and I've worked extensively with DMA, event-based architectures, and energy metering devices. If you're looking to create an innovative IoT solution or need a custom embedded system developed from the ground up, let's talk!
