I'm a passionate software engineer and developer. I love to learn and focus on improving.
My goal in any project is to create expandable, maintainable and efficient software.

Technology and computers are at the core of my work, life, and hobbies. I strive to be a part of open-source development and technological progress.

Respect the cognitive endurance of coworkers and your future self. Clean-up, don't overcomplicate, aim for readability over brevity.
