Senior Software Engineer and Systems Architect with 15+ years of hands-on experience in commercial development. My core expertise spans native software, microcontroller firmware, and electronic hardware. For the past 10 years, I have been helping my Upwork clients create new products from scratch and implement new features in existing software and hardware products. ■ Embedded Systems and Firmware ▪ Core experience: - Complex business logic & advanced control algorithms - Distributed control systems, machine networking (M2M) - High-performance / low-latency control - Secure, reliable, real-time interprocess communication (IPC) • Typical stack: - C, C++ (C++11/17), STL (except that needs heap memory allocation) - IAR for ARM, Keil + ARM/Clang, GCC for ARM, STM32CubeIDE - ThreadX RTOS (preferred), FreeRTOS, mbed, mbedTLS - No HAL from STM32 in production firmware ■ Native Desktop Applications and C++ Backend Software • Specialization: - High-performance GUI applications based on the Qt Framework (QtWidgets) - Console applications (CLI - command-line interface) - Standalone applications (no GUI or command-line interface) - Windows services and system applications - Any of the above combined into a complex via interprocess communication (IPC) • Typical stack: - C++11/23, STL, Qt6, Boost, ICU, rich own codebase - Microsoft Visual Studio, Microsoft Visual Studio Code - SQL DBMS: Oracle, Postgres, SQLite, MySQL, MS-SQL ● Other - Strong focus on design quality, reliability, and maintainability - Recent domains: IoT, AgTech, Automotive, Manufacturing, Defense, Energy - Recent tech: LoRa, GSM, LTE, LTE-M, Ethernet, RS-485, Modbus, CAN, CAN FD - Recent STM32 MCUs: STM32H7 (single/dual-core), STM32F4, STM32L4, STM32G4 Keywords: C++ C Multithreading IPC Qt Framework Socket IP TCP UDP PPP SSL TLS PLC SCADA MCU Microcontroler STM32 RTOS FreeRTOS ThreadX AVR UART USART CAN LIN Modbus Ethernet SPI I2C DMA RS-232 RS-485 DMA Sensor 12V 24V 48V 5V 3V 3V3 Drone FPV UAV UGV ESC Ardupilot Betaflight Pixhawk PX4 LRS ELRS S.BUS SBUS CRSF Crossfire Radio GSM SMS LTE LTE-M GPS GNSS LoRa Serial Port FTDI FT232 OGG OPUS Vorbis Speex WAV WinAPI WinSock mbed mbedtls Serialization AES DES 3DES GOST USB RFID

I was or still am involved in many projects : - vending machines firmware development for major Italian coffee machines producer, using Qt and STM, - MMORPG game server development from ground up for upcoming new game, - big MES (Manufacturing Execution System) project. The system was designed by our team and is constantly expanded to meet customers' needs. I enjoy gamedev, UI, programming daemons, servers and communications programs. I find it easy to write in any environment.

I help businesses, startups and founders design and build complete software systems, from embedded devices and IoT solutions to backend services, web platforms, desktop applications and mobile apps. Every project starts with understanding your business goals. Based on your requirements, I help select the right architecture and technology stack to build solutions that are reliable, maintainable and ready to grow. I can help with: Software architecture and technical consulting Embedded firmware and IoT systems Backend, web, desktop and mobile applications Hardware and software integration Legacy system modernization and technology migration Monitoring, diagnostics and long-term technical support Documentation and knowledge transfer for your team If you're looking for a software engineer who can take ownership of a project from architecture and implementation to deployment and ongoing support, I'd be happy to discuss your ideas.
