About Me
I have been interested in IT since high school, when I created scripts for GTA San Andreas multiplayer servers as a hobby. Later, I completed software development training, followed by an intensive full-stack course at Green Fox Academy. I then worked as a software developer in Hungary before moving to Ireland to pursue international opportunities. I am currently continuing to develop my skills, with a particular focus on modern web technologies and practical engineering projects.
