Antonios Vatousis#

Junior IT Engineer | SysAdmin Enthusiast | Data Operations#

Welcome to my digital portfolio and documentation hub. I am an undergraduate student at the University of Ioannina (Department of Informatics & Telecommunications) with a hands-on approach to technology.

My focus isn't just on writing code, but on understanding the infrastructure that runs it. I document my journey, my fixes, and my projects to bridge the gap between theory and real-world application.

🚀 What I Do#

  • System Administration: Managing Linux (Debian/Ubuntu) environments, Docker containers, and Self-Hosted services (Home-Lab).
  • Data & Backend: Building REST APIs (Node.js), managing Databases (MySQL), and automating data reporting (Excel/ERP).
  • Open Source: contributing to the localization of privacy-focused tools.

📂 Key Sections#

📚 My Knowledge Base#

The core of this website. A collection of technical notes, troubleshooting guides, and documentation for Linux, Docker, and various software setups.

🎬 Project: Movie Tracking App#

A Full Stack web application (Node.js & MySQL) for tracking movies and TV series, featuring user authentication and gamification.
