IoT - PCB Layout- Embedded systems developer

Hello, I am an electronic technologist with +3 years of experience in PCB layout, R&D, and embedded systems development. My passions are the IoT, domotics, and the development of electronic hardware. I specialize in PCB design and microcontroller programming for IoT, automation, control, and data acquisition applications. I have advanced knowledge of C and C++. I specifically highlight my experience working with: • Communication protocols: USB, RF, UART, I2C, SPI, MQTT. • Acquisition and processing of biomedical signals (ECG, PPG, PCG). • WiFi and BLE modules (CC3100, ESP8266, ESP32). • Microcontrollers (Arduino, Tiva TM4C123, Tiva TM4C1294, Teensy 3.2). • Sensors (LM35, DHT11, PIR HC-SR501, ACS711KEXLT-15AB-T, etc...). • Programming language: C, C++. • Design of voltage regulators and UPS. My goal is to deliver quality work according to the needs of the client to ensure their satisfaction and establish a professional relationship that allows the development of future projects.
