You have some knowledge since you've done a few aspects of Technical Writing so maybe brush up on the different types of documentation. https://documentation.divio.com/. Take a look at Amruta's process on writing a Technical Document. https://www.youtube.com/playlist?list=PLoynTxuTLXaBs05-A4rlEC9ijs9ZzSxRP. Then look at some products/tools you're interested in or in your industry and write three documentation samples. A mix of tutorials, how-to, and explanation guides would be a great start. I took an online course, which helped me create three portfolio pieces with instructor feedback. I don't want to break any rules sharing it here but feel free to DM me.
