Bank of Gotham City
In 2011, I developed my first website; it was a test project for my university's faculty.
I used various web technologies that were available and the best practices at the time. Afterwards, I became really invested in the project so I incorporated more features into it. That's the story of how my first web project started and how I got my first taste of web development.
The project is a bank management system called The Bank of Gotham City (an artificial bank).
Technology Stack: PHP, MySQL, CSS, JavaScript, HTML
