I do high performance front end work, but there's no public access to my best projects, and my work from years ago is absolutely terrible. I haven't been in job-search mode in years but I'm fairly certain people are going to want to see a good portfolio. Not sure where to go from here.
Isn't most produced output at work company confidential? A financial analyst won't open books to a new company during an interview. A devops person won't draw complete architecture diagrams either. Personally I don't understand why the web industry seems to think one has to do extra work on evenings and weekends (hobby projects) to be presentable. When somebody tells me they work on an internal tool or intranet of a large company I have to take their word for it, no way they can show me screenshots. At best I'd get a list of technologies used and can ask generic questions about those.
