Embedded systems architect with extensive experience designing, developing, and mass-producing mission-critical electronic products for the energy, utilities, security, and oil & gas sectors. I've successfully delivered 8+ commercial hardware products currently deployed at scale across hundreds of field units. My work spans the full product lifecycle — from concept and R&D, through circuit design and PCB layout, to firmware development and mass manufacturing. Core expertise: - Microcontrollers: ESP32, STM32, ARM Cortex, Arduino - PCB Design: from schematic to production-ready Gerbers - Firmware: C/C++, FreeRTOS, OTA remote updates, MQTT, device drivers - Communication: LoRa, BLE, Wi-Fi, Cellular (2G/3G/4G), Satellite, VHF, RS485 - Sensors: Ultrasonic, seismic, acoustic, optical, temperature, pressure, current/voltage - IoT & Cloud: AWS IoT, MQTT, web dashboards - Power: Solar, ultra-low power design, battery management, energy harvesting All my firmware deliverables include a built-in OTA (Over-The-Air) update system with a web-based MQTT management interface — fully developed and field-tested across hundreds of devices. Highlights: - 3 technology patents (gas metering, ultrasonic measurement, optical coding) - Petrobras Inventor of the Year award - National Innovation Award (CNI - Brazil) - International publication (Society of Petroleum Engineers) - Postgraduate specialization in Artificial Intelligence I deliver production-ready solutions — not just prototypes.
