AnonymousA. Charles Dickens is the author of that book.
I believe this one is correct. It is "timeless" as you say. An action like writing a book and being its author cannot be undone and therefore present tense is correct. It doesn't matter if the author is alive or dead, he is associated with that book, so he is the author.

He was the author would imply he isn't its author anymore which I guess could only be possible if he isn't considered the author anymore.

For your specific situation, I believe you are still the author of that employer's software even if you don't work for that employer anymore. So C. is the obvious choice.
Thank you, CristianC, that was really helpful.

I was also wondering if a native speaker would agree with what has been explained or perhaps share his/her thoughts on my questions. Thanks so much.

Just a follow-up question, considering that Charles Dickens, in fact, passed away, can I still use A?
If you were to write this sentence, which would you choose personally, is or was?
