Hello and welcome!
check out the game jams, many of them are held online and you can participate remotely. There are a ton of them. It’s a great way to meet other developers and have fun and then have a finished product to show your work. Another great thing to do is to take unity projects, some of the free project games, like Angry Bots, and do sound replacements on those games, in the engine, so you can show off captured gameplay footage. Anyhow, good luck!
