Hello, I'm a Full-Stack Web Developer & a UI/UX Designer from Poland.
Oh and I also do translations, I guess?
I have been making websites since at least 2017-10-15, although websites that I made back then were not good.
I use HTML, CSS and JavaScript for my frontend, and LAMP (Linux/Apache/MySQL/PHP) for my backend. I also have some experience with:

I build a lot of projects for different people, including Kasztan Space, Kasztan TK and Kasztan Pro.
I made a lot of projects for myself too, you can see them on the projects page.
I also translated some applications from English to Polish, such as CPU-L, GPU-L and DogeHouse - an Open Source project.
