Something about me

Hey, I'm Jiří (Jira, j1r4). I've been programming for over 5 years. I have already finished high school and graduated from the IT class. I am now studying Cybersecurity at Masaryk University in Brno. It's my first year. I am still actively programming and learning new things, while continuing to improve my skills in web development and software engineering. In the past, I've worked on several personal and learning projects, including websites and game-related tools, and I continue to build my experience through practical work and self-improvement. I also successfully created a full commercial project website for a game server owner and I have been actively maintaining it for almost a year. You can find more information about my projects in the 'WEB Projects' section.

Why should you choose me?

I am a motivated student with programming experience. I enjoy building reliable, modern solutions and I am always eager to learn new technologies, improve my skills, and keep growing in the field of cybersecurity and software development. For my age, I believe my English, communication skills, and programming abilities are above average. I am capable of creating reliable and high-quality websites despite my young age. As a student, I have a strong desire to learn and explore new things. I also have experience working on various projects, which allows me to quickly adapt to new situations and collaborate effectively with others.
