RFID & Arduino Prototype Developer Needed (Embedded Systems)
We are looking for a skilled developer with hands-on experience in RFID and Arduino-based embedded systems. The ideal candidate should be comfortable working with RFID readers, tags, and microcontroller programming for prototype development. Experience integrating sensors, serial communication, SPI, I2C, and UART peripherals is highly preferred. You should be able to design, test, and troubleshoot both hardware and firmware efficiently. Knowledge of C/C++ programming for Arduino platforms and debugging embedded applications is required. Experience with ESP32, STM32, or similar microcontrollers is a strong advantage. Familiarity with access control, asset tracking, inventory management, or IoT applications using RFID is a plus. This is a remote freelance opportunity with flexible hours and the potential for ongoing projects. Please include a brief summary of your relevant experience and examples of similar RFID or Arduino projects you have completed.
