Hobby C/C++ Embedded and desktop systems developer, currently work on my own GUI toolkit. More you need to know only if you hire me ;)
Microcontrollers: I have experience in programming microcontrollers, particularly the AVR-based, which I continue to develop as a hobby. But most of my practice is in development for ARM-based platforms, like STM32, NXP. I have experience working with microcontrollers based on another RISC ISA's, mostly 8-bit platforms. To work with microcontrollers, I mostly use only text editor, debugger, analyzer, compiler, profiler and firmware upload utils, work on as low level as possible for maximum control and performance.
Native Development: I prefer native development using C/C++, mostly for desktop development. For backend applications and services, I most often use C and C++. Also most of projects depends of platform specific solutions, so I have experience with API like Win32API, Cocoa, some Linux/Unix API's on different levels, GUI, integration, threading, network stack.
Web Development: Not my special interest but I've worked with the Vue.js framework on several projects, focusing on frontend and backend development.
C, C++, Objective-C, Objective-C++, Pascal, Ada
Basic knowledge of git and GitHub.
I am proficient in Linux, *nix'es, macOS, and Windows, with skills in system administration, scripting, and workflow optimization.
I am constantly seeking to expand my knowledge, integrate new tools and technologies, and achieve high-quality results through enhanced efficiency.
