For those interested in what powers this portal: vadnica.org is not built on WordPress or any other ready-made system. Every line of code, from PHP and MySQL logic to complex JavaScript functions, was hand-written in the PhpStorm environment. Why? Because I wanted full control over speed, security, and architecture.
The portal is based on proven technologies used in a modern and efficient way:
The heart of my approach is the interactive simulators. The MySQL simulator does not use server calls for every query; instead, it is based on 9,306 lines of unique JavaScript code that simulates database operations directly in your browser. This enables instant results and a 100% safe environment for experimentation.
Because the simulators run locally, you cannot damage any database. You can delete, update, and create tables without worry – all within a safe sandbox I built with a passion for clean programming.
