-# Hi there
+I am a software engineer with a background in materials science and scientific computing.
 
-My name is Radek and I'm the author of this theme. I made it to help you present your ideas easier.
+I currently work at UKG as a Java Backend Engineer. My interests span backend systems, developer tooling, Linux workflows, and performance-oriented programming.
 
-We all know how hard is to start something on the web, especially these days. You need to prepare a bunch of stuff, configure them and when that’s done — create the content.
+I write here about practical engineering lessons, tools I use, and projects I build.
-
-This theme is pretty basic and covers all of the essentials. All you have to do is start typing!
-
-The theme includes:
-
-- fully customizable color schemes generated by [**terminal.css**](https://panr.github.io/terminal-css/).
-- great reading experience thanks to [**Fira Code**](https://github.com/tonsky/FiraCode).
-- nice code highlighting thanks to [**PrismJS**](https://prismjs.com) that matches the theme's color scheme.
-
-So, there you have it... enjoy!
