Hi Lucas here

I'm a 26-year-old software developer from Poland.

I'm passionate about full-stack development, and I love bringing ideas to life by building clean, functional, and scalable applications. Whether it’s crafting a smooth user interface or diving deep into backend logic, I enjoy the entire development process.

Outside of coding, I’m a gamer at heart — I find games not only entertaining but also inspiring, especially when it comes to design and mechanics. I also enjoy exploring new technologies, tools, and experiences that push me to grow both personally and professionally. Whether it's picking up a new framework, diving into a new hobby, or simply trying something out of my comfort zone, I’m always curious and eager to learn.

I value creativity, continuous improvement, and meaningful collaboration — both in code and in life.
