ADP Retirement Services first generation of PES (Plan Entry System) program. It was/is an internal tool with all the horror stories that you hear about internal tools. The people who made it wrote obscure logic with encrypted variable naming with the main purpose of having job security, it's a core tool in their business model but treated like gutter trash, built with visual basic and embedded angular code to make it look more modern, the supposed rewrite talk went on for 8 years, and to put icing on the top it was QAd/maintained by underqualified offshore old-school contractors (you cant even call this group devs/engineers).
