Automatic Documentation Creation Application

Developed a desktop application for the automatic creation of paper documentation for products of a factory. Previously, all the paperwork was done manually, resulting in inefficiency and significant time loss — 2-3 hours of paperwork per employee daily.

The application I created resulted in notable time savings, reducing to 10-20 minutes of time spent daily. The clients continue to provide positive system feedback in 2021.
