The PGI (Personal Global Inventory) is a website developed by Arizona State University which uses statistical analysis techniques developed at the university to help students analyze their aptitudes in different areas and choose careers based off of this analysis.

This website uses Drupal forms and Views to present question sets to the user, and an extensive custom PHP solution to analyze the answers provided and display various metrics, including a graph image generated on the fly.

I contributed to this project by designing and building the PHP analyzer to calculate the presented results. I also optimized this solution and took extensive advantage of Drupal's built-in caching system.
