A selfie! I’m smiling at the camera, wearing a green dress, and sitting in front of a large amount of green foliage. It’s a sunny day and shining both on the side of my face and the plants.

Hi, I’m Alex.

I’m a software developer at Wellcome Collection, a free museum and library in London. I help to search and store the collections, with a particular interest in digital preservation.

I have a fairly active online presence – I tweet a lot, and my blog is where I share ideas that don’t fit into a tweet. You can read my posts on the web, or subscribe to them as an RSS feed.

I write about anything I find interesting or fun – there’s plenty of programming, but lots of other stuff too. Past topics include accessibility, Chinese dictionaries, and Welsh waterfalls.

If you’d like to see everything I’ve been up to, my projects page is a good starting point. It includes links to everything I’ve published online.

I’m trans, genderfluid, and my pronouns vary. If you’re not sure, “they/them” is a safe default.

I hope you enjoy the site.
