Fabio B.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

With 25+ years of experience, I design commercial and industrial products, ensuring all design, prototyping, and manufacturing requirements are met. I am Italian and currently live in Spain. My daily job is to investigate and develop new technologies. You can benefit from my expertise if you need innovation. I provide better technologies, better ideas, and better problem-solving. I am a skilled electronic engineer, multi-language developer, inventor, and circuit designer with a background in Linux/BSD servers administration and network administration. My work ranges from developing space-grade electronic prototypes to deploying and managing large-scale data networks of IoT sensors, and designing autonomous robotics with AI. AI + LLM + custom tools + IoT sensors: I can building custom agents with specific trained LLMs and coding custom tools in C/C++ for real-time processing and reporting of data from custom-designed IoT sensors. Technologies and Projects: - Nordic nRF52/53/54 Bluetooth BLE chips and nRF9161/51 LTE SoC with CAT-M1 and NB-IoT - ARM Cortex-M33, ultra-low power IoT designs with LTE, LoRa, Bluetooth, and 5uA during sleep - IoT designs with various sensors, IMU fusion, and motion sensors - BOARDS: Beaglebone Black, Raspberry Pi, ODROID, Arduino, Teensy, Spresense - MCU: NXP, STM32, Nordic, TI, and Silabs ARM Cortex-M MCUs - RF SOCs: Semtech and Nordic Semiconductors - Design and optimization of electronic circuits and PCB layouts for CE, FCC, UL compliance tests - In 2018, I conducted a market analysis of a key electronic-component supplier, combining industry expertise with insights gathered from engineers during product development. I identified misleading signals about the component’s longevity and recommended ending the commercial relationship before a $1.4M supply commitment. When the supplier discontinued the product without notice the following year, my analysis was validated, helping the client avoid losses of more than $1M. - Design of avionics for a space satellite - Design of space-grade solar panels with solar cells for space applications Software and Firmware Programming: - Zephyr RTOS, Nordic Connect SDK and Nuttx RTOS - Custom embedded Linux OS with Yocto project - Servers with Linux OS (Raspberry Pi, ODROID, ARM-based): Ubuntu, Debian, ArchLinux, FreeBSD, NetBSD - AI + Machine learning, TinyML or emlearn on ARM Cortex-M33 MCUs - Computer vision on NVIDIA Jetson boards - PX4, MAVLINK, ROS, and GAZEBO simulators - Python (NumPy + Pandas), C, C++, Lua, Perl, FastAPI REST API via HTTPS and authentication - MATLAB, Octave Capabilities and Services: - Custom RF circuits and antennas on PCB, tested with a Vector Network Analyzer (VNA) - SMT soldering, prototyping, and PCB assembly with a pick-and-place machine; inspections with a microscope - Contacts for PCB fabrication and massive production globally - Machine learning (AI) in microcontrollers running inference in custom firmware, and training in the cloud on ARM Cortex-M33 MCUs - Returning, invited speaker for the BSD Foundation, discussing BSD operating systems worldwide at annual conventions in Europe and North America - Private git server for managing customer files as remote-accessible repositories, allowing them to track daily status Key Project Areas: - IoT and Sensor Networks: - XBEE, Bluetooth BLE, WiFi, LTE, LoRa, LoRaWAN, Iridium satellite modems (SBD) - Autonomous robots (ocean and ground) - Wearable devices - Tracking devices with sensors - Electronics and Circuits: - Solar panels design, lithium battery rechargers with safety - Industrial heavy-duty protocols and power electronics, encoders and motor drivers, automotive electronics, aerospace electronics, RF, and avionics design, machine learning on MCUs - CAN bus, RS485, 5-20mA protocols, audio MIDI instruments design, heterogeneous multicore architectures, JTAG, SWD, GDB, openocd, Segger J-Link - DSP algorithms - Hardware and Manufacturing: - Multilayer PCB layout designs - CAD with FEM analysis, 3D-printed enclosures for electronics - Compliance and Market Analysis: - Design and optimization of electronic circuits and PCB layouts for CE, FCC, UL compliance tests
