A picture of a person set against the sky.

Hi, I’m Alex.

I’m a software developer at the Wellcome Trust. I’m helping to build a platform for searching and storing our digital collections. It’s taking Wellcome’s assets – books, archives, images, and more – and presenting them through consistent, well-designed APIs.

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

The blog is a place for me to hone my writing skills, and write about anything I find interesting – there’s plenty of programming, but a lot of other stuff as well. Past topics include accessibility, braille, Chinese dictionaries, and Welsh waterfalls.

Sometimes I give talks at meetups or conferences, and I have a list of slides/videos from my past talks.

I’ve also written about my ideas for running inclusive and accessible events.

I’m trans, genderfluid, and my pronouns vary. If you don’t know me, “they/them” is a safe default.

I hope you enjoy the site.
