Embedded Systems Engineer, ESP32 STM32 PCB Full Stack Developer
I will develop reliable firmware for ESP32, STM32, Arduino, and custom embedded systems. I can help with new product development, code cleanup, debugging, sensor integration, communication protocols, and feature upgrades. I work with UART, I2C, SPI, WiFi, BLE, MQTT, and serial communication. I can also troubleshoot unstable code, boot issues, and hardware software integration problems. Please message me before ordering if your project uses custom hardware or advanced requirements.
