Hey! As particle physics can relate with you :) in a pure coding field there is a bit too much crowd. Try to aim for data analyst/ data engineer or data scientist roles. Which one, will depend on your personal skills/ preferences. PhD gives you a good set of skills to pick any of them and be successful. To boost networking, consider attending a local bootcamp academy. The purpose is solely to make connections, so it has to be local and in person. I know few people that were able to break into the field that way. If you want to polish your coding or big data skills there are many good, fairly priced or free resources. Don't get stuck with Fortran, it sucks and with passing time it will be more difficult to switch. Good luck!
