Hello World!

Hey, I'm Krzysztof Sobolewski, a CS student from Poland. I’m into Java, web development, and solving algorithmic problems for fun. I love building stuff and figuring out how things work under the hood. Always learning and experimenting, whether it's a new framework, a tricky algorithm, or just a cool side project.

A basic REST API built with Spring Boot, with Mockito tests included. Nothing groundbreaking, just a simple project I made to get comfortable with Spring Boot and learn the backend fundamentals.

Lox

A free and open-source password manager — simple, yet powerful. Built with Python, SQLite, and Textual, it keeps your passwords safe and organized without unnecessary complexity.

undead vision

A 2D rogue-like horror game developed in WPF using C#. Created in 48 hours during a Game Jam, with the theme "Vision". The main mechanic? Limited visibility, with only a lamp to light your way — so watch your back!

...and many more projects on my GitHub, from small experiments to bigger, more complex builds. Feel free to check them out!
