As a high school student, I was a professional Magic: The Gathering player, which also transitioned into me selling my own cards on an online store. After struggling with keeping inventory, I built a Magic: The Gathering inventory manager that you could input all of your cards into, including search queries based on anything on a card. Additionally, I built features such as being able to submit a list of cards for a deck and determine which cards I already had and which I still needed and a GUI to show all of the information. I wrote the whole project using Java, along with an Apache database, and using the Netbeans IDE to build my own GUI.
