Hi there, welcome! 👋

You might want to follow some dev-related accounts, hashtags and groups (you can find lots of them listed at https://fedi.directory/computing-technology ).

Once you've followed a few accounts, tags and groups, these should bring lots more accounts into your timeline which you can follow too.

There is also lots more info here on how to make your own account more discoverable: https://fedi.tips/how-do-i-get-more-followers-on-mastodon-and-the-fediverse/
