Driving Innovation in Embedded Systems & IoT | Expert Hardware & Firmware Solutions for Your Tech Vision Hello! I'm Nelson Fortunatti, a passionate and results-driven Electronics Engineer with a Specialist degree and I have completed the courses of the Master's in Embedded Systems (UBA). I transform complex technological challenges into tangible, market-ready solutions. My expertise spans the entire product lifecycle – from meticulous hardware (PCB) design and robust firmware development to seamless connectivity and system integration. With over 8 years in the Embedded Systems field, I've had the privilege of: Architecting & Deploying Large-Scale IoT Systems: I was instrumental in developing and maintaining an advanced farm irrigation system (ESP32, FreeRTOS/ESP-IDF, LoRaWAN/Cat-M1, MQTT, AWS IoT Core) with over 2,000 units successfully deployed across Australia. This involved managing a codebase exceeding 60,000 lines of C++ and ensuring robust FOTA updates. Designing High-Reliability Hardware: I've engineered sophisticated smart battery systems for demanding applications like scientific and military drones, capable of handling 150A continuous currents (e.g., 14-16s batteries with BQ34z100, BQ76952, DroneCAN). Developing Innovative Prototypes: My work includes creating novel wearable technology, such as a tick repellent device with microcontroller-activated reservoirs and smartphone connectivity. Creating Intuitive User Interfaces & Control Systems: I've designed complete control systems, like a Heat Pump Controller based on Raspberry Pi with a QT C++/QML capacitive touch interface. Fostering Academic & Commercial Innovation: At ITBA, I contributed to teaching, mentored final projects, and developed custom electronic and mechatronic devices for external companies. I offer expert consulting and development services to bring your electronic product vision to life. Whether you're at the conceptual stage, need a complex prototype, or are looking to scale for mass production, I provide: Full Product Lifecycle Development: From idea to production-ready design. Embedded Firmware & Software: Bare-metal, RTOS (FreeRTOS, ESP-IDF), Linux (Yocto, drivers), C/C++, Python. Custom Hardware & PCB Design: Analog/digital circuits, power electronics, DFM/DFA, using Altium, Kicad, Eagle, EasyEDA. IoT & Connectivity Solutions: LoRaWAN, Cat-M1, Wi-Fi, Bluetooth, MQTT, AWS IoT Core, Node-RED. System Integration & Testing: Ensuring all components work harmoniously. Why Partner With Me?
