About

Hi, my name is Michal and I'm a programmer — it's always been this way. Back in ninth grade, my brother gave me my first HTML and CSS book, and the excitement of building websites began. My first project was a site about my dog, hard-coding CSS with no idea that LESS and SCSS even existed. In high school and later at university, I dove into PHP and the Nette Framework, even building my own CMS system. I then spent 10 years at a telecommunications and payment services company, where I expanded my skills in backend development with Node.js and Perl, Dockerization, and DevOps. I love programming and tackling complex problems — designing structures and processes that make life simpler for everyone involved.
