As a POC I removed all client specifics from a project and made it reusable. Thousands of lines of code. In a day. From a project I knew nothing about in a language I previously used only in school. And it compiled and ran in the end.

Ripping out so much useless code felt great, possibly as good as creating something new, fresh, innocent. I improved on performance and maintenability and found some errors in the process.

After a successfull POC it was time to do it properly. That was a nightmare. A horror movie you want to see through. In the end I felt even better.
