Pay equity analysis tools from vendors can cost thousands per year. I built one for free in 8 hours using vibe coding — without any programming experience. The tool runs multiple linear regression, calculates adjusted pay gaps across gender and race, identifies underpaid employees, and generates executive-ready PDF reports. This case study covers the full journey from product requirements document to live deployment, including the bugs, the fixes, and lessons learned for HR professionals curious about AI-assisted development.

To have fun with vibe coding I have created a Cat-Ching, a free online fortune reading app that combines 3,000 years of ancient Chinese wisdom with modern AI technology to deliver personalized spiritual guidance and life advice. Whether you're seeking clarity on career decisions, relationship questions, or personal growth, Cat-Ching lets you cast hexagrams using virtual coin tossing or manual entry, then provides authentic Wilhelm-Baynes translations alongside AI-powered interpretations tailored to your specific situation.

This post is about a framework I use to build their own analytical tools and dashboards using AI-driven “vibe coding.” I try to explain my fellow HR pros how to try and transform traditional workflows into applications, instead of using Excel or other MS Office tools.
