⭐5 years as C++/C# developer in supply chain industry ⭐2 years as Unreal Engine 5 developer in porting co-development company ⭐Godot and GDevelop on Upwork ✨Hobbiest indie game developer. On my way to first commercial release Supply chain industry experience taught me how to write laconic, effective and supportable code. I use OOP, SOLID, IOC for guidance, and know my way around design patterns. I was designing and developing REST API to ensure backend communication with in-house developed frontend. Before that I assisted with support of huge monolithic application. When working as an Unreal Engine developer I was dealing with platform-specific APIs, wrote tools for designers, and adapted old UE3 systems to work in new UE5 project. It will be a pleasure for me to help with your project. Write me and we will create something fabulous!

I'm an italian electronic engineer with more than 15 years of work experience. I work as HW designer; FW and SW developer. As HW designer, I work in Altium, KiCad and Orcad and I have experience in development single MCU (Microchip PIC, ARM Cortex, ESP32) boards with several digital I/O (GPIO, UART, SPI, I2C, PWM,....) and some analog I/O. I design complete board: power section, MCU section, peripheral section,.... I design also boards with battery power; so I have experience in low power PCB design. I have also experience in commercial boards (Arduino, Raspberry, Beaglebone,...) shields design. I have also experience in bluetooth (both 2.0 and 4.0) PCB design. As FW developer, usually I work in C for Eclipse + GNU ARM GCC for different ARM Cortex M0/M0+/M3/M4/M33 manufacturers (STM32Fx, NXP, EFM32/EFR32 SiLabs, Nordic nFR5x, but I'm ready to learn new frameworks). I have also good experience with ESP32 in "esp-idf" framework. I work with both single task (bare metal) and multi task environment (FreeRTOS, RTX,...). I write code for low level driver (GPIO, UART, SPI, I2C, PWM....) management, for medium level (driver for sensor, MEMS, memories, fuel gauge, display,...) and for high level/final application, for bootloader and for OTA. I work also in "C code" commercial boards Arduino/Linux embedded commercial boards (Raspberry and Beaglebone). I have also experience in bluetooth (both 2.0 and 4.0) programming. All my code is covered by unit/integration/stress tests. As SW developer, I work in C, C++, .NET, Java, and lot of others programming languages. Mainly I work for Windows O.S., but I have experience in Linux development too. I have experience in openCV library for image/video processing. I have experience in Android App development with Java (Eclipse + Android SDK + Java).
