I told my boss I had an idea for a program that could improve efficiency across much of the business, and he let me build it on company time. In the long term, he wanted to be able to sell it to other companies. However, the program never got implemented due to personnel mismanagement, and I’d rather be able to post it on my github under a free licence so I can use it as a resume item, and at least someone would have the chance to actually use it. It’s all still in my head, and I could write it again if I wanted. If I do, is it illegal to publish it? What if I write it in a different language? Do I need to change the variable names? I did plenty of research and planning on company time to build it, and it’s not like I can research it again, it’s all still in my head.
The problem is I learned how to write good code at university and I used what I learned to inform the software architecture. I could write garbage that gets the same job done but isn’t maintainable, except for the fact that I want to show this off as a display of my skill. I already did the best I could do on the company clock. If I do the best I can do again, it’ll be the same. I can’t make significant changes outside of language, variables, and dependencies, because then it wouldn’t be as good. The structure I made for the company is simply good design. I don’t remember every detail of the structure, but if I tried to rebuild it I’d get the same result. This is a problem with a correct answer.
