Hello, I’m Alex—a seasoned software developer and hardware engineer with a passion for technology that began when I was just 13 years old. I specialize in creating high-performance desktop applications for Windows, Linux, and macOS using the Qt framework and C++, and I excel in designing visually appealing GUIs that enhance user experiences. What I Offer: 1. Desktop Software Development: I deliver native, high-performance desktop applications complete with meticulously crafted source code. My expertise in GUI design, particularly with Qt projects, ensures that your software not only performs well but also looks great. 2. Embedded Systems & IoT Development: From PCB schematics and layouts to BOMs and firmware, I provide comprehensive solutions for embedded systems and IoT devices. My work with STM microcontrollers and Espressif’s ESP32, along with proficiency in communication protocols like UART, SPI, I2C, CAN, and Ethernet, guarantees robust and reliable device operation. 3. Hardware Prototyping & Production: I offer advanced hardware prototyping services using Fusion 360, complemented by the production of prototype test samples through 3D printing and CNC machining. This allows for rapid iteration and precise development of your hardware projects. 4. Technical Documentation & Custom Integration: Beyond delivering essential project files, I create detailed technical documentation, design intuitive user interfaces, and develop custom integrations. For example, I can design a production automation device to expand an existing machine’s capabilities—integrating it seamlessly by designing parts in Fusion 360, producing them via 3D printing, and crafting a comprehensive user manual. Technical Skills: Programming Languages: C/C++, C#, PHP, Python, Delphi/Pascal, JavaScript/TypeScript, Java/Kotlin, Assembler. Design & Prototyping Tools: Qt Creator, Fusion 360, EasyEDA, 3D printing, CNC machining. I pride myself on writing clear, maintainable code and maintaining effective communication with clients and team members. To demonstrate my capabilities and ensure your project is perfectly tailored to your needs, I prefer to start by producing a custom example based on your specifications. This initial proof of concept helps build trust and ensures that my work meets your expectations from the outset.

The best freelancer I've come across, and an outstanding App developer. Delivered my project in time, and he's a guy who expects money after delivering work. The quality of work was also excellent.
