PayDirt

A historical NFL data archive/analysis tool.

About

PayDirt was created as a group database design and implementaion project for one of my classes in the Fall 2025 semester. The requirements were to design and implement a database using Microsoft SQL Server. App integration was optional, but I opted to use the opportunity to learn my first bit of web development, and the result is PayDirt.

Architecture

PayDirt is a web app written in JavaScript implemented with Node.js and Express. Both the server and interface are written in "vanilla" JavaScript (no frameworks) and the HTML and CSS is all hand-written.

The app was originally written to use SQL Server, but that was choking the life out of my poor server, so I decided to rewrite it to use SQLite instead. Now why colleges still teach 20-year-old material and don't actually recommend a practical solution, I couldn't tell you. But I'm happy with where it's landed.
