I've recently completed a job that I would like to show in my resume or website, mostly as a testament to my skills and of course self-promotion. My data contains private information that, if found published, may create a dispute with my client. I don't want to sour our relationship over something like this but I need to promote myself.
I was thinking of just changing the names of the different features and of course the client's name and change the private data (I've thought some montecarlo simulations or such) but it's such a sensitive subject (mining industry) it may be falsely interpreted by any common onlooker.
Any suggestions are well received.
TLDR: How to publish a website to serve my business ends without compromising my clients trust by publishing sensitive data?
