Diamond analytics platform with automated PDF generation.
The client needed to generate complex, pixel-perfect PDF certificates for diamonds based on dynamic GIA data. Doing this manually was slow and prone to human error.
I built a NestJS microservice using Puppeteer to programmatically render HTML templates into PDFs. We utilized Google Sheets API as a CMS, allowing admins to update diamond inventory in real-time without database access.
"Automated 95% of the manual reporting work and reduced report generation time from 10 minutes to 5 seconds."
