This is great advice, I would add one more thing: Start actually working on things. The OP says he/she has not worked on anything outside of academia worth putting on a resume. It is not too late to start a project or working relationship that is a good conversation starter for an industry job. There are so many ways one could do this, you could go to a site like https://www.catchafire.org/ https://www.catchafire.org/ and volunteer your technical skills to a non-profit in need. You could get involved with an open source project. You could also start a project on your own. The first two are preferable to the last because the first two involve actually meeting and working with other people (you need to meet other people to get a job, obviously) but any of them would be a good first step. The other thing I would say is you probably don't need a huge project or a flashy achievement to help yourself be viewed as someone worth giving a job offer. Your phD is going to legitimize your computing knowledge, you just have to show yourself to be interested in also being practical.
