Super Olefins - COA Generator
Internal desktop tool that produces standardised certificates of analysis from a library of 300+ templates.
The client
Super Olefins is a chemical manufacturer. Every batch that leaves the plant travels with a certificate of analysis - the document that states what was tested, against which specification, with what result. Different products and different customers need different certificate formats, and the team was maintaining more than three hundred of them by hand.
What we built
An internal desktop application that holds all of those templates in one place and generates a finished, standardised certificate from the batch data.
- A single library of 300+ COA templates, searchable and versioned.
- Form-driven generation - pick the product and template, enter the batch results, get the certificate.
- PDF export in the exact layout each customer expects, every time.
- Runs offline on the quality team’s machine; no cloud dependency for a document that has to be produced whether or not the network is up.
How it was built
React for the interface, Electron.js to ship it as a desktop application, and a PDF generation layer for output. It replaced a folder of Word documents with a tool that produces the same certificate the same way, which is what a customer’s incoming inspection wants to see.
