Welcome Seamus Donnellan. I can't wait to read your articles when you publish it.
Hashnode created a place where members of the developer community request for articles. I am sure you will be able to find a topic to write about there.
You can also map your hashnode blog to your own custom domain as well. For example:
Welcome, Seamus! I can't wait to read your next posts! 🚀
