Just finished sailing the world aboard sailinghannahpenn.co.uk.

Now working at lightbug.io

Previously a staff software engineer working for Wikimedia Deutschland on various projects including Wikibase, Wikidata and MediaWiki.

My side projects are numerous, and you can read about them on a dedicated page.

I use the username “addshore” in most places, such as GitHub, Mastodon, Twitter, Keybase & Wikimedia. Hence the name of this site.

Take a look at my latest posts or various projects.

You can also get in touch with me using my contact page.
